FRP Storage Tanks:
FRP Storage Tanks are built to last
FRP storage tanks offer :
Reliability Corrosion resistance Advanced engineering designs for both aboveground and belowground storage tanks.
UL Listed single-wall and double-wall construction are available for many industries. Double-wall tanks can accommodate a wide array of high-tech electronic leak monitoring and stored product control equipment.
FRP aboveground tanks are ideal for:
Acids Caustics Solvents and non-flammable corrosive fluids in petroleum production, chemical, pulp and paper, and other industrial applications FRP Shop Fabricated Aboveground Tank sizes range from 40 to 60,000 gallons in capacity.
Field erected sizes are larger.
Environmentally Safe Will Never Rust Durable Long Life
FRP Underground Tanks are ideal for:
Gasoline Jet Fuel AV-Gas Motor Oil Kerosene Diesel Fuel Alcohol-Gasoline Blend Motor Fuels Ethanol-Blend
Motor Fuels
Methanol Blends Oxygenated Motor Fuels Water & Septic Any Gasoline/Ethanol Blend, including 100% Ethanol, Methanol or M85
FRP Underground Tank sizes range from 285 to 50,000 gallons in capacity, and from 4 to 12 feet in diameter and 6-1/2 to 73 feet in length.
Why use FRP?
The MAIN characteristics of thermo sets (literally ‘setting under heat’) is that they require curing, when they undergo a molecular cross-linking process which is irreversible and renders them infusible. They thus offer high thermal stability, plus good rigidity and hardness and resistance to creep. It also means that, once cured, the resin and its laminate cannot be reprocessed, except by methods of chemical break-down, which are currently under active development. For practical purposes, therefore, cured thermosetting resins can be recycled most effectively if ground to fine particles, when they can be incorporated into new laminates, as cost-effective fillers.
Thermosetting resins have little use as pure resin, but require addition of other chemicals to render them process able. For reinforced plastics, the compounds usually comprise a resin system (with curing agents, hardeners, inhibitors, plasticizers) and fillers and or reinforcement. The resin system provides the ‘binder’, to a large extent dictating the cost, dimensional stability, heat, chemical resistance and basic flammability. The reinforcement can influence these (particularly heat-and dimensional-stability), but the man effect is on tensile strength and toughness. High-performance fibres, of course, have a fundamental influence on cost. Special fillers and additives can influence mechanical properties, especially for improvement in dimensional stability, but they are mainly used to confer specific properties, such as flame retardancy, UV stability or electrical conductivity.
Thermosetting resins are normally used in the liquid state and solidify and harden on curing. With some resins it is possible to part-cure and then hold the resin in what is termed the B-stage, for the cure to be completed at later time.
