About composite

Composites are two or more materials with markedly different physical or chemical properties combined in a way that they act in concert, yet remain separate and distinct at some levels because they don’t fully merge or dissolve into one another.

 

Not all plastics are Composites. In fact, the majority of plastics today are pure plastic, like toys and soda bottles. When additional strength needed, many types of plastics can be reinforced (usually with reinforcing fibers). This combination of plastic and reinforcement can produce some of the strongest materials for their weight that technology has ever developed and the most versatile.

 

Therefore, Composites, also referred to as fiber-reinforced polymer (FRPComposites is a combination of a

 

 

such that there is a sufficient aspect ratio (length to thickness) to provide a discernable reinforcing function in one or more directions. FRP Composite may also contain:

 

  • fillers
  • additives
  • core materials

 

that modify and enhance the final product. The constituent elements in a Composite retain their identities (they don't dissolve and merge completely into each other) while acting in concert to provide a host of benefits such as:

 

  • Lightweight
  • High strength
  • Corrosion resistant
  • High strength to weight ratio

Benefits of composites

LIGHT WEIGHT

 

Composites compared to most woods and metalsare are light in weight. Their lightness is important in automobiles and aircraft, for example, where less weight means better fuel efficiency (more miles to the gallon). People who design airplanes are greatly concerned with weight, since reducing a craft’s weight reduces the amount of fuel it needs and increases the speeds it can reach. Some modern airplanes are built with more Composites than metal including the new Boeing 787, Dreamliner.

 

HIGH STRENGTH

 

Composites can be designed to be far stronger than aluminum or steel. Metals are equally strong in all directions. But Composites can be engineered and designed to be strong in a specific direction.

 

STRENGTH RELATED TO WEIGHT

 

Strength-to-weight ratio is a material’s strength in relation to how much it weighs. Some materials are very strong and heavy, such as steel. Other materials can be strong and light, such as bamboo poles. Composite materials can be designed to be both strong and light. This property is why Composites are used to build airplanes — which need a very high strength material at the lowest possible weight. A Composite can be made to resist bending in one direction, for example. When something is built with metal, and greater strength is needed in one direction, the material usually must be made thicker, which adds weight. Composites can be strong without being heavy. Composites have the highest strength-to-weight ratios in structures today.

 

CORROSION RESISTANCE

 

Composites resist damage from the weather and from harsh chemicals that can eat away at other materials. Composites are good choices where chemicals are handled or stored. Outdoors, they stand up to severe weather and wide changes in temperature.

 

HIGH-IMPACT STRENGTH

 

Composites can be made to absorb impacts the sudden force of a bullet, for instance, or the blast from an explosion. Because of this property, Composites are used in bulletproof vests and panels and to shield airplanes, buildings, and military vehicles from explosions.

 

DESIGN FLEXIBILITY

 

Composites can be molded into complicated shapes more easily than most other materials. This gives designers the freedom to create almost any shape or form. Most recreational boats today, for example, are built from fiberglass Composites because these materials can easily be molded into complex shapes, which improve boat design while lowering costs. The surface of Composites can also be molded to mimic any surface finish or texture, from smooth to pebbly.

 

PART CONSOLIDATION

 

A single piece made of Composite materials can replace an entire assembly of metal parts. Reducing the number of parts in a machine or a structure saves time and cuts down on the maintenance needed over the life of the item.

 

DIMENSIONAL STABILITY

 

Composites retain their shape and size when they are hot or cool, wet or dry. Wood, on the other hand, swells and shrinks as the humidity changes. Composites can be a better choice in situations demanding tight fits that do not vary. They are used in aircraft wings, for example, so that the wing shape and size do not change as the plane gains or loses altitude.

 

NONCONDUCTIVE

 

Composites are nonconductive, meaning they do not conduct electricity. This property makes them suitable for such items as electrical utility poles and the circuit boards in electronics. If electrical conductivity is needed, it is possible to make some Composites conductive.

 

NONMAGNETIC

 

Composites contain no metals; therefore, they are not magnetic. They can be used around sensitive electronic equipment. The lack of magnetic interference allows large magnets used in MRI (magnetic resonance imaging) equipment to perform better. Composites are used in both the equipment housing and table. In addition, the construction of the room uses Composites rebar to reinforced the concrete walls and floors in the hospital.

 

RADAR TRANSPARENT

 

Radar signals pass right through Composites, a property that makes Composites ideal materials for use anywhere radar equipment is operating, whether on the ground or in the air. Composites play a key role in stealth aircraft, such as the U.S. Air Force’s B-2 stealth bomber, which is nearly invisible to radar.

 

LOW THERMAL CONDUCTIVITY

 

Composites are good insulators—they do not easily conduct heat or cold. They are used in buildings for doors, panels, and windows where extra protection is needed from severe weather.

 

DURABLE

 

Structures made of Composites have a long life and need little maintenance. We do not know how long composites last, because we have not come to the end of the life of many original Composites. Many Composites have been in service for half a century.

History of the composites industry

The use of natural composite materials has been a part of man's technology since the first ancient builder used straw to reinforce mud bricks.

 

The 12th century Mongols made the advanced weapons of their day with archery bows that were smaller and more powerful than their rivals. These bows were Composites structures made by combining cattle tendons, horn, bamboo and silk which bonded with natural pine resin. The tendons were placed on the tension side of the bow, the bamboo was used as a core and sheets of horn were laminated to the compression side of the bow. The entire structure was tightly wrapped with silk using the rosin adhesive. These 12th century weapons designers certainly understood the principles of Composite design. In recent times some of these 700 year old museum pieces were strung and tested. They were about 80% as strong as modern Composite bows.

 

In the late 1800s canoe builders were experimenting with gluing together layers of kraft paper with shellac to form paper laminates. While the concept was successful, the materials did not perform well. Because the available materials were not up to the job, the idea faded.

 

In the years between 1870 and 1890, a revolution was occurring in chemistry. The first synthetic (man-made) resins were developed which could be converted from a liquid to a solid by polymerization. These Polymer resins are transformed from the liquid state to the solid state by crosslinking the molecules. Early synthetic resins included celluloid, melamine and Bakelite.

 

Composites are no longer considered "space-age" materials utilized only for stealth bombers and space shuttles. This versatile material system has become a part of everyday life. In fact, Composites are so widely used and in such varied of applications, the overall Composites market had to be divided in the following major commercial segments to cover its thousands of products.

Manhole

Why are manholes called manholes?

 

The term "manhole" comes from the simple idea of how the hole was used--by men who entered the hole to locate the tunneled area beneath the ground. A manhole may also be called an access chamber, utility hole, maintenance hole or inspection chamber.

 

 

 

A manhole (alternatively utility hole, cable chamber, maintenance hole, inspection chamber, access chamber, sewer hole, smellhole, flabhole, ding-dong or confined space) is the top opening to an underground utility vault used to house an access point for making connections, inspection, valve adjustments or performing maintenance on underground and buried public utility and other services including sewers, telephone, electricity, storm drains, district heating and gas.

 

What is Manhole ?

Manholes are masonry or RCC chambers constructed at suitable intervals along the sewer lines for providing access into them.

Purposes of Manhole

  1. They are used to carry out inspection, cleaning and removing obstruction in the sewer line. 
  2. Manhole allows joining of sewers or changing the direction of sewer or alignment of sewer or both.
  3. They allow the escape of considerable gases through perforated cover and thus help in ventilation of sewage.
  4. They facilitate the laying of sewer line in convenient lengths.

Location of Manhole

  1. Manhole is provided when
  2. There is change in grade of sewer
  3. There is change in alignment
  4. There is change in size of sewer
  5. At junction of two or more sewers
  6. Manhole is also provided in straight alignment of sewers at regular intervals depending upon the diameters of sewers. It ranges from 90m to 150m (300' – 500') e.g. 75m for 60cmф, 120m for 90cmф and 150m for 120cmф.

Types of Manhole

Depending upon the depth the manhole can be classified as;

1. Shallow manhole

It is provided at shallow depth of 75-90cm (2'-3'). It is provided at the beginning of branch sewer or at a place not subjected to heavy traffic. It is provided with a light cover at its top it is also called inspection chamber.

 

2. Normal Manhole

 

It is provided in sewer line at depth of 150cm with a heavy cover on its top. It is generally of square shape (or rectangular shape).

 

3. Deep Manhole

 

They are provided at depth greater than 150cm with heavy cover at the top. The size is gradually increased and a facility for going down is provided.

 

 

 


 

 

 

Usages of Manhole

 

 

 

Manhole closings are protected by a manhole cover, a flat plug designed to prevent accidental or unauthorized access to the manhole. Those plugs are traditionally made of metal, but may be constructed from precast concrete, glass reinforced plastic or other composite material (especially in Europe, or where cover theft is of concern).

 

 

 

Manholes are usually outfitted with metal, polypropylene, or fiberglass steps installed in the inner side of the wall to allow easy descent into the utility space. Because of legislation restricting acceptable manual handling weights, Europe has seen a move toward lighter weight composite manhole cover materials, which also have the benefits of greater slip resistance and electrical insulating properties.

 

 

 

The access openings are usually circular in shape to prevent accidental fall of the cover into the hole.

 

 

 

Manholes are generally found in urban areas, in streets and occasionally under sidewalks. In rural and undeveloped areas, services such as telephone and electricity are usually carried on utility poles or even pylons rather than underground.

 

 

 

Composite manholes

 

 

 

Composite (fiberglass) manholes are commonly used in applications where infiltration, exfiltration, or corrosion by hydrogen sulfide (from sewer gas) are a concern, or where structures need to be factory integrated into a manhole before placement.

 

 

 

Structures commonly integrated into composite manholes include:

 

 

 

  • Flow inverts
  • Flumes
  • Drop structures from higher elevation flows to lower elevation discharge pipes

 

 

 

Occasionally, composite manholes will integrate:

 

 

 

  • Weirs
  • Storm water screening structures
  • Sewage grinders
  • Energy absorbing structures to dissipate undesirable flow stream turbulence or velocity

 

 

 

Hazards caused by stray voltage in manholes

 

 

 

In urban areas, stray voltage issues have become a significant concern for utilities. In 2004, Jodie S. Lane was electrocuted after stepping on a metal manhole cover, while walking her dog in New York City.

Composite Manhole Covers

Manhole cover

From Wikipedia, the free encyclopedia


 

A manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.

Manhole covers date back at least to the era of ancient Rome, which had sewer grates made from stone.

Description

Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 50 kilograms (110 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorised people not having suitable tools to remove them.

Manhole covers may also be constructed from glass-reinforced plastic or other composite material (especially in Europe, or where cover theft is of concern). Because of legislation restricting acceptable manual handling weights, Europe has seen a move towards lighter weight composite manhole cover materials, which also have the benefits of greater slip resistance and electrical insulating properties.

A manhole cover sits on metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.

The covers usually feature "pick holes", into which a hook handle tool is inserted to lift them. Pick holes can be concealed for a more watertight lid, or can allow light to shine through. A manhole pick or hook is typically used to lift them, though other tools can be used as well, including electromagnets.

Although the covers are too large to be easily collectible, their ubiquity and the many patterns and descriptions printed on them has led some people to collect pictures of covers from around the world. According to Remo Camerota, the author of a book on the subject titled Drainspotting, 95% of Japanese municipalities have their own cover design, often with colorful inlaid paint.

Despite their weight and cumbersome nature, manhole covers are sometimes stolen, usually for resale as scrap, particularly when metal prices rise.

Shape

Circular

The question of why manhole covers are typically round (in some countries) was made famous by Microsoft when they began asking it as a job-interview question. Originally meant as a psychological assessment of how one approaches a question with more than one correct answer, the problem has produced a number of alternative explanations, from the tautological ("Manhole covers are round because manholes are round.") to the philosophical.

Reasons for the shape include:

  • A round manhole cover cannot fall through its circular opening, whereas a square manhole cover may fall in if it were inserted diagonally in the hole. The existence of a "lip" holding up the lid means that the underlying hole is smaller than the cover, so that other shapes might suffice. (A Reuleaux triangle or other curve of constant width would also serve this purpose, but round covers are much easier to manufacture.)
  • Round tubes are the strongest and most material-efficient shape against the compression of the earth around them, and so it is natural that the cover of a round tube assume a circular shape.
  • A round manhole cover has a smaller surface than a square one, thus less material is needed to cast the manhole cover, meaning lower cost.
  • The bearing surfaces of manhole frames and covers are machined to assure flatness and prevent them from becoming dislodged by traffic. Round castings are much easier to machine using a lathe.
  • Circular covers do not need to be rotated to align with the manhole.
  • A round manhole cover can be more easily moved by being rolled.
  • A round manhole cover can be easily locked in place with a quarter turn (as is done in countries like France), which makes them hard to open without a special tool. Lockable covers do not have to be made as heavy, because traffic passing over them cannot lift them up by suction.

Other

Other manhole shapes can be found, usually squares or rectangles. Nashua, New Hampshire, may be unique in the United States for having triangular manhole covers that point in the direction of the underlying flow. The city is phasing out the triangles, which were made by a local foundry, because they are not large enough to meet modern safety standards and a manufacturer for larger triangles cannot be found. Some manhole covers in Hamilton, Bermuda, are triangular, and hinged. Some triangular water-main covers also exist in San Francisco.

Security and safety

See also: Urban exploration and Stray voltage

Because of concerns about unauthorized access to underground spaces, manhole covers may be locked down, or even temporarily spot-welded in place. This practice has become routine in some locales, as advance preparation for official parades and similar events attracting large crowds or important people.

In urban areas, stray voltage issues have become a significant concern for utilities. In 2004, Jodie S. Lane was electrocuted after stepping on a metal manhole cover, while walking her dog in New York City. As result of this and other incidents, increased attention has been focused on these hazards, including technical conferences on stray voltage detection and prevention.

Interaction with race cars

Because of their aerodynamic design, some modern racing cars create enough vacuum to lift a manhole cover off its recess. During races on city streets, manhole covers must therefore be welded or locked down to prevent injury. In 1990, during the Group C World Sportscar Championship race at Circuit Gilles Villeneuve (located in a public park in Montréal, Quebec), a Brun Motorsport Porsche 962 struck a manhole cover that was lifted by the ground effect of the car he was following, a Courage C24 Porsche. This caused the trailing Porsche to catch fire, and safety issues ended the race shortly afterwards.

 

Propelled into space

According to urban legend, a manhole cover was accidentally launched from its shaft during an underground nuclear test in the 1950s, at great enough speed to achieve escape velocity. The myth is based on a real incident during the Operation Plumbbob nuclear tests, where a 900-kilogram (1,984 lb) steel plate cap was blasted off the test shaft at an unknown velocity, and appears as a blur on a single frame of film of the test; it was never recovered. A calculation before the event gave a predicted speed of six times Earth escape velocity, but the calculation is not likely to have been accurate. After the event, Dr. Robert R. Brownlee described the best estimate of the cover's speed from the photographic evidence as "going like a bat out of hell!

 

Use for navigation

A robotics research paper in 2011 suggested that robots could examine the shapes of specific manhole covers and use them to calculate their geographic position, as a double-check on GPS data.

Manufacturing process

The manufacturing process of metal manhole covers consists of six steps:

  1. Design and simulation
  2. Patterns
  3. Moulding
  4. Melting
  5. Finishing
  6. Quality control.

Water Tank

Water Tank

A water tank is a container for storing liquid. The need for a water tank is as old as civilization, to provide storage of water for use in many applications, drinking water, irrigation agriculture, fire suppression, agricultural farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. Water tank parameters include the general design of the tank, and choice of construction materials, linings. Various materials are used for making a water tank: plastics (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon, or stainless). Earthen pots also function as water storages. Water tanks are an efficient way to help developing countries to store clean water.

History

Throughout history, wood, ceramic and stone have been used as water tanks. These containers were all naturally occurring and some man made and a few of these tanks are still in service. The Indus Valley Civilization (3000–1500 BC) made use of granaries and water tanks. Medieval castles needed water tanks for the defenders to withstand a siege. A wooden water tank found at the Año Nuevo State Reserve (California) was restored to functionality after being found completely overgrown with ivy. It had been built in 1884.

Types

Chemical contact tank of FDA and NSF polyethylene construction, allows for retention time for chemical treatment chemicals to "contact" (chemically treat) with product water.

Ground water tank, made of lined carbon steel, may receive water from a water well or from surface water, allowing a large volume of water to be placed in inventory and used during peak demand cycles.

Elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 cm or 1 psi per 2.31 feet of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most domestic and industrial requirements.

Vertical cylindrical dome top tanks may hold from 200 litres or fifty gallons to several million gallons. Horizontal cylindrical tanks are typically used for transport because their low-profile creates a low center of gravity helping to maintain equilibrium for the transport vehicle, trailer or truck.

A Hydro-pneumatic tank is typically a horizontal pressurized storage tank. Pressurizing this reservoir of water creates a surge free delivery of stored water into the distribution system.

Design

By design a water tank or container should do no harm to the water. Water is susceptible to a number of ambient negative influences, including bacteria, viruses, algae, changes in pH, and accumulation of minerals, accumulated gas. The contamination can come from a variety of origins including piping, tank construction materials, animal and bird feces, mineral and gas intrusion. A correctly designed water tank works to address and mitigate these negative effects.

A safety based news article linked copper poisoning as originating from a plastic tank. The article indicated that rain water was collected and stored in a plastic tank and that the tank did nothing to mitigate the low pH. The water was then brought into homes with copper piping, the copper was released by the high acid rainwater and caused poisoning in humans. It is important to note that since the plastic tank is an inert container, it has no effect on the incoming water. Good practice would be to analyze any water source periodically and treat accordingly, in this case the collected acid rain should be analyzed, and pH adjusted before being brought into a domestic water supply system.

The release of copper due to acidic water is monitored may be accomplished with a variety of technology, beginning with pH strips and going to more sophisticated pH monitors, indicate pH which when acidic or caustic, some with output communication capabilities. There is no "linkage" between the plastic tank and copper poisoning, a solution to the problem is easy, monitor 'stored rainwater' with 'swimming pool strips' cheap and available at, swimming pool supply outlets. If the water is too acidic, contact state/county/local health officials to obtain advice and precise solutions and pH limits and guidelines as to what should be used to treat rainwater to be used as domestic drinking water.

Articles and specifications for water tank applications and design considerations, the AWWA (American Water Works Association) provides details as required by many states to complete a certification process to insure the quality of water being consumed.

The American Water Works Association is a reservoir of water tank knowledge; the association provides specifications for a variety of water storage tank applications as well as design. The AWWA's site provides scientific resources with which the reader will be able to develop an informed perspective on which to make decisions regarding their water tank requirements.

Storage tank

From Wikipedia, the free encyclopedia

 

 

Storage tanks are containers that hold liquids, compressed gases (gas tank) or mediums used for the short- or long-term storage of heat or cold. The term can be used for reservoirs (artificial lakes and ponds), and for manufactured containers. The usage of the word tank for reservoirs is uncommon in American English but is moderately common in British English. In other countries, the term tends to refer only to artificial containers.

In the USA, storage tanks operate under no (or very little) pressure, distinguishing them from pressure vessels. Storage tanks are often cylindrical in shape, perpendicular to the ground with flat bottoms, and a fixed or floating roof. There are usually many environmental regulations applied to the design and operation of storage tanks, often depending on the nature of the fluid contained within. Above ground storage tanks (AST) differ from underground (UST) storage tanks in the kinds of regulations that are applied.

Reservoirs can be covered, in which case they may be called covered or underground storage tanks or reservoirs. Covered water tanks are common in urban areas.

Storage tanks are available in many shapes: vertical and horizontal cylindrical; open top and closed top; flat bottom, cone bottom, slope bottom and dish bottom. Large tanks tend to be vertical cylindrical, or to have rounded corners transition from vertical side wall to bottom profile, to easier withstand hydraulic hydrostatically induced pressure of contained liquid. Most container tanks for handling liquids during transportation are designed to handle varying degrees of pressure.

A large storage tank is sometimes mounted on a lorry (truck) or on an articulated lorry trailer, which is then called a tanker.

Special features

 

 

Cylindrical fuel storage tank with fixed roof and internal floating roof. Capacity approx 2,000,000 litres

Since most liquids can spill, evaporate, or seep through even the smallest opening, special consideration must made for their safe and secure handling. This usually involves building a bunding, or containment dike, around the tank, so that any leakage may be safely contained.

Some storage tanks need a floating roof in addition to or in lieu of the fixed roof and structure. This floating roof rises and falls with the liquid level inside the tank, thereby decreasing the vapor space above the liquid level. Floating roofs are considered a safety requirement as well as a pollution prevention measure for many industries including petroleum refining.

In the United States, metal tanks in contact with soil and containing petroleum products must be protected frocorrosion to prevent escape of the product into the environment. The most effective and common corrosion control techniques for steel in contact with soil is cathodic protection.

For refineries

Tanks for a particular fluid are chosen according to the flash-point of that substance. Generally in refineries and especially for liquid fuels, there are fixed roof tanks, and floating roof tanks.

1.   Fixed roof tanks are meant for liquids with very high flash points, (e.g. fuel oil, water, bitumen etc.) Cone roofs, dome roofs and umbrella roofs are usual. These are insulated to prevent the clogging of certain materials, wherein the heat is provided by steam coils within the tanks. Dome roof tanks are meant for tanks having slightly higher storage pressure than that of atmosphere (e.g. slop oil).

2.   Floating roof tanks are broadly divided into external floating roof tanks (usually called floating roof tanks: FR Tanks) and internal floating roof types (IFR Tanks).

IFR tanks are used for liquids with low flash-points (e.g., ATF, MS. gasoline, ethanol). These tanks are nothing but cone roof tanks with a floating roof inside which travels up and down along with the liquid level. This floating roof traps the vapor from low flash-point fuels. Floating roofs are supported with legs or cables on which they rest. FR tanks do not have a fixed roof (it is open in the top) and has a floating roof only. Medium flash point liquids such as naphtha, kerosene, diesel, and crude oil are stored in these tanks.

One of the common types found in mining areas is the open roof type tank, usually to store ore slurries. These are the easiest storage tanks to build.

Other classifications which can be made for storage tanks are based upon their location in a refinery:

·         COT- crude oil tankages

·         PIT- product and intermediate storage tankages

·         DISPATCH- dispatch area tankages

·         UTILITIES- tanks made in the power plant area, for storage water etc.

·         OSBL tanks- the first 3 types come under out side battery limit tankages

·         ISBL tanks- these are usually mini tanks which are found in the production units of a refinery (as neutralisation tanks, water tanks etc.)

As flash-points of fuels go very low the tanks are usually spherical (known as spheres), tom store LPG, hydrogen, hexane, nitrogen, oxygen etc.

Other types of tank

Atmospheric

An atmospheric tank is a container for holding a liquid at atmospheric pressure. The major design code for welded atmospheric tanks are API 650 and API 620. API 653 is used for analysis of in-service storage tanks. In Europe the design code is Eurocode 3 (EN 1993), part 4-2.

High pressure

 

Horizontal, cylindrical shell, elliptical heads carbon steel pressure vessel

In the case of a liquefied gas such as hydrogen or chlorine, or a compressed gas such as compressed natural gas or MAPP, the storage tank must be made to withstand the sometimes immense pressures exerted by the contents. These tanks may be called cylinders and, being pressure vessels, are sometimes excluded from the class of "tanks".

Thermal storage tanks

One form of seasonal thermal energy storage (STES) is the use of large surface water tanks that are insulated and then covered with earth berms to enable the year-round of solar-thermal heat that is collected primarily in the summer for all-year heating. A related technology has become widespread in Danish district heating systems. The thermal storage medium is gravel and water in large, shallow, lined pits that are covered with insulation, soil and grass.

Ice and slush tanks are used for short-term of cold for use in air conditioning, allowing refrigeration equipment to be run at night when electric power is less expensive, yet provide cooling during hot daytime hours.

Milk tank

In dairy farming a bulk milk cooling tank is a large storage tank for cooling and holding milk at a cold temperature until it can be picked up by a milk hauler. The bulk milk cooling tank is an important milk farm equipment. It is usually made of stainless steel and used every day to store the raw milk on the farm in good condition. It must be cleaned after each milk collection. The milk cooling tank can be the property of the farmer or being rented to the farmer by the dairy plant.

Septic tank

A septic tank is part of a small scale sewage treatment system often referred to as a septic system. It consists of the tank and a septic drain field. Waste water enters the tank where solids can settle and scum floats. Anaerobic digestion occurs on the settled solids, reducing the volume of solids. The water released by the system is normally absorbed by the drain field without needing any further treatment.

Mobile "storage" tanks

While not strictly a "storage" tank, mobile tanks share many of the same features of storage tanks. Also, they must be designed to deal with a heavy sloshing load and the risk of collision or other accident. Some of these include ocean-going oil tankers and LNG carriers; railroad tank cars; and the road and highway traveling tankers. Also included are the holding tanks which are the tanks that store toilet waste on RVs and boats.

Materials of construction

While steel and concrete remain one of the most popular choices for tanksglass-reinforced plasticthermoplastic and polyethylene tanks are increasing in popularity. They offer lower build costs and greater chemical resistance, especially for storage of speciality chemicals. There are several relevant standards, such as British Standard 4994 (1989), DVS (German Welding Institute) 2205, and ASME (American Society of Mechanical Engineers) RTP-1 which give advice on wall thickness, quality control procedures, testing procedures, accreditation, fabrication and design criteria of final product.

Tank failures

There have been numerous catastrophic failures of storage tanks, one of the most notorious being that which occurred at Boston Massachusetts USA on January 14, 1919. The large tank had only been filled eight times when it failed, and resulting wave of molasses killed 21 people in the vicinity. The Boston molasses disaster was caused by poor design and construction, with a wall too thin to bear repeated loads from the contents. The tank had not been tested before use by filling with water, and was also poorly riveted. The owner of the tankUnited States Industrial Alcohol Company, paid out $300,000 (nearly $4 million in 2012 ) in compensation to the victims or their relatives.

There have been many other accidents caused by tanks since then, often caused by faulty welding or by sub-standard steel. New inventions have at least fixed some of the more common issues around the tanks' seal. However, storage tanks also present another problem, surprisingly, when empty. If they have been used to hold oil or oil products such as gasoline, the atmosphere in the tanks may be highly explosive as the space fills with hydrocarbons. If new welding operations are started, then sparks can easily ignite the contents, with disastrous results for the welders. The problem is similar to that of empty bunkers on tanker ships, which are now required to use an inert gas blanket to prevent explosive atmospheres building up from residues.

Etymology

The word "tank" originally meant "artificial lake" and came from India, perhaps via Portuguese tanque. It may have some connection with:

  • Some Indian language words similar to "tak" or "tank" and meaning "reservoir for water". In Sanskrit a holding pond or reservoir is called a tadaka. Gujarati talao means "man-made lake". These uses of the word were incorporated into the English language.
  • The Arabic verb istanqa`a اِسْتَنْقَعَ = "it [i.e. some liquid] collected and became stagnant".

Fiberglass

Fiberglass

From Wikipedia, the free encyclopedia
 
For the thermal insulation material sometimes called fiberglass, see glass wool. For the glass fiber itself, also sometimes called fiberglass, see glass fiber. For similar composite materials in which the reinforcement fiber is carbon fibers, see carbon-fiber-reinforced polymer.

Fiberglass (or fibreglass) is a type of fiber-reinforced plastic where the reinforcement fiber is specifically glass fiber. The glass fiber may be randomly arranged, flattened into a sheet (called a chopped strand mat), or woven into a fabric. The plastic matrix may be a thermosetting plastic – most often epoxy, polyester resin – or vinylester, or a thermoplastic.

The glass fibers are made of various types of glass depending upon the fiberglass use. These glasses all contain silica or silicate, with varying amounts of oxides of calcium, magnesium, and sometimes boron. To be used in fiberglass, glass fibers have to be made with very low levels of defects.

Fiberglass is a strong lightweight material and is used for many products. Although it is not as strong and stiff as composites based on carbon fiber, it is less brittle, and its raw materials are much cheaper. Its bulk strength and weight are also better than many metals, and it can be more readily molded into complex shapes. Applications of fiberglass include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, casts, surfboards, and external door skins.

Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GFK . Because glass fiber itself is sometimes referred to as "fiberglass", the composite is also called "fiberglass reinforced plastic." This article will adopt the convention that "fiberglass" refers to the complete glass fiber reinforced composite material, rather than only to the glass fiber within it.

History

Glass fibers have been produced for centuries, but mass production of glass strands was accidentally discovered in 1932 when Games Slayter, a researcher at Owens-Illinois, directed a jet of compressed air at a stream of molten glass and produced fibers. A patent for this method of producing glass wool was first applied for in 1933. Owens joined with the Corning company in 1935 and the method was adapted by Owens Corning to produce its patented "fibreglas" (one "s") in 1936. Originally, fibreglas was a glass wool with fibers entrapping a great deal of gas, making it useful as an insulator, especially at high temperatures.

A suitable resin for combining the "fibreglass" with a plastic to produce a composite material was developed in 1936 by du Pont. The first ancestor of modern polyester resins is Cyanamid's resin of 1942. Peroxide curing systems were used by then. With the combination of fiberglass and resin the gas content of the material was replaced by plastic. This reduced the insulation properties to values typical of the plastic, but now for the first time the composite showed great strength and promise as a structural and building material. Confusingly, many glass fiber composites continued to be called "fiberglass" (as a generic name) and the name was also used for the low-density glass wool product containing gas instead of plastic.

Ray Greene of Owens Corning is credited with producing the first composite boat in 1937, but did not proceed further at the time due to the brittle nature of the plastic used. In 1939 Russia was reported to have constructed a passenger boat of plastic materials, and the United States a fuselage and wings of an aircraft. The first car to have a fiber-glass body was a 1946 prototype of the Stout Scarab, but the model did not enter production.

Fiber

Glass reinforcements used for fiberglass are supplied in different physical forms, microspheres, chopped or woven.

Unlike glass fibers used for insulation, for the final structure to be strong, the fiber's surfaces must be almost entirely free of defects, as this permits the fibers to reach gigapascal tensile strengths. If a bulk piece of glass were defect-free, it would be equally as strong as glass fibers; however, it is generally impractical to produce and maintain bulk material in a defect-free state outside of laboratory conditions.

Production

The process of manufacturing fiberglass is called pultrusion. The manufacturing process for glass fibers suitable for reinforcement uses large furnaces to gradually melt the silica sand, limestone, kaolin clay, fluorspar, colemanite, dolomite and otherminerals to liquid form. It is then extruded through bushings, which are bundles of very small orifices (typically 5–25 micrometres in diameter for E-Glass, 9 micrometres for S-Glass). These filaments are then sized (coated) with a chemical solution. The individual filaments are now bundled in large numbers to provide a roving. The diameter of the filaments, and the number of filaments in the roving, determine its weight, typically expressed in one of two measurement systems:

  • yield, or yards per pound (the number of yards of fiber in one pound of material; thus a smaller number means a heavier roving). Examples of standard yields are 225yield, 450yield, 675yield.
  • tex, or grams per km (how many grams 1 km of roving weighs, inverted from yield; thus a smaller number means a lighter roving). Examples of standard tex are 750tex, 1100tex, 2200tex.

These rovings are then either used directly in a composite application such as pultrusion, filament winding (pipe), gun roving (where an automated gun chops the glass into short lengths and drops it into a jet of resin, projected onto the surface of a mold), or in an intermediary step, to manufacture fabrics such as chopped strand mat (CSM) (made of randomly oriented small cut lengths of fiber all bonded together), woven fabrics, knit fabrics or uni-directional fabrics.

Chopped strand mat

Chopped strand mat or CSM is a form of reinforcement used in fiberglass. It consists of glass fibers laid randomly across each other and held together by a binder.

It is typically processed using the hand lay-up technique, where sheets of material are placed in a mold and brushed with resin. Because the binder dissolves in resin, the material easily conforms to different shapes when wetted out. After the resin cures, the hardened product can be taken from the mold and finished.

Using chopped strand mat gives a fiberglass with isotropic in-plane material properties.

Sizing

A coating or primer is applied to the roving to:

  • Help protect the glass filaments for processing and manipulation.
  • Ensure proper bonding to the resin matrix, thus allowing for transfer of shear loads from the glass fibers to the thermoset plastic. Without this bonding, the fibers can 'slip' in the matrix, causing localized failure.
