Dry chlorine has a great affinity for absorbing moisture, and wet chlorine is extremely corrosive, attacking most common materials except HasteUoy C, titanium, and tantalum. These metals are protected from attack by the acids formed by chlorine hydrolysis because of surface oxide films on the metal. Tantalum is the preferred constmction material for service with wet and dry chlorine. Wet chlorine gas is handled under pressure using fiberglass-reinforced plastics. Rubber-lined steel is suitable for wet chlorine gas handling up to 100°C. At low pressures and low temperatures PVC, chlorinated PVC, and reinforced polyester resins are also used. Polytetrafluoroethylene (PTFE), poly(vinyhdene fluoride) (PVDE), and...

An 80 m3 tank fiberglass-reinforced plastic acid tank was blown apart at the base as the result of overpressure. The vent had been slip-plated so the tank could be entered for inspection. The steel slip-plate was covered with a corrosion-resistant sheet of polytetrafluoroethylene. Afterward, when the slip-plate was removed, the sheet was left behind. This did not matter at the time, as the tank was also vented through an oveiflow line,... 

Tanks made from fiberglass-reinforced plastic are being increasingly used, but a number of failures have occurred. In the United Kingdom 30 catastrophic failures are known to have occurred during the period 1973-1980, and a 1996 report shows that they seem to have been continuing at a similar rate [21J. The following typify the catastrophic failures that have occurred [11] ... 

H = History if a plant has used material successfully for many years, and the staff members know its strengths and limitations, how to weld it, etc., hesitate before making a change. For example, a fiberglass-reinforced plastic had given excellent service for many years when another composite from the same company, with the same name but a different number, was used instead, it failed overnight.

For facilities susceptible to the contamination of nitroglycerin liquids and vapors, basic construction materials of wood framing, reinforced concrete, fiberglass reinforced plastic, and sandwich panels were chosen for development of architectural details incorporating lead conductive floor lining, equipment doors, personnel escape chutes and doors, ceiling and wall interfaces, interior finishes, joint sealing, door and wall louvers, wall vents, wall penetrations, and fixed windows. 

For facilities susceptible to nitrocellulose, single base and multibase dusts, the same details could be used with the addition of alternate basic construction types. Six types of construction were chosen which included wood frame, concrete masonry units, reinforced concrete, modified preengineered buildings, fiberglass reinforced plastic and sandwich panels. These were chosen for development of architectural details similar to those mentioned above for nitroglycerin facilities except troweled-on conductive floor lining was to be used instead of lead. 

Note that glazing is acrylic plastic to comply with the AMC Safety Manual requirements. Screws for attachment of wood door frames and vision panel stops are countersunk and caulked. Joints not taped are sealed with caulking. It should be noted here that Sunflower AAP has had major problems with exterior wood doors exposed to the weather. A recurring problem has been the delamination of wood door materials. This may require a change to a more weather-resistant door material such as fiberglass reinforced plastic. Details for doors of this material are included in the standard architectural details. 

Figure 15 is a new standard design for a fiberglass reinforced plastic (FRP) escape chute which replaces existing sheet metal escape chutes. This design was based on a standard detail furnished by the Corps of Engineers, Huntsville Division. 

Fiberglass reinforced plastic (FRP) is used in composite systems. It is particularly important in the process industry because of its corrosion resistance and light weight. The epoxy resin in the FRP matrix begins to melt at approximately 150°C (302°F). This may be used as a first-order failure criterion. Failure of empty 5-mm thick FRP pipes in 2-6 minutes has been reported (SINTEF,...

REINFORCED PLASTICS. Reinforced plastics are commonly referred to as composites or, more specifically, polymer composites, Not all composites are reinforced plastics ceramic/metal-matrix composites and concrete are good examples of nonpolymeric composites. Reinforced plastics are also referred to RP, FRP (fiberglass-reinforced plastic), and GRP (glass-reinforced plastic) interchangeably.

As the war drew to a close, Owens-Corning began to plan for peacetime uses of its fiberglass products. In 1946, it introduced fiberglass-reinforced fishing rods, serving trays, acoustical tiles, and pleasure boats. And in 1953, it announced production of the first commercial automobile, the Chevrolet Corvette, with a body made entirely of polymer matrix composite, a fiberglass reinforced plastic. 

The resin matrix can be either thermosetting or thermoplastic. Thermosetting resins such as epoxy, polyimide, polyester, and phenolic are used in applications where physical properties are important. Polyester and epoxy composites make up the bulk of the thermoset composite market. Of these two, polyesters dominate by far. Reinforced with glass fiber, these are known as fiberglass-reinforced plastics (FRPs). FRPs are molded by layup and spray-up methods or by compression molding either a preform or sheet molding compound (SMC).
