Fiberglass Tanks

With over 60 years' experience, Endurance combines engineering and chemical expertise to provide our Endurance Composites brand of fiberglass tanks with cost-efficiency and extreme corrosion resistance. Our manufacturing capabilities include replacement and new construction fiberglass (FRP/GRP) tanks including:

Chemical processing tanks
Scrubbers
Vessels
Seal Pots
Stacks
Tank internals in FRP, Fluoropolymer or thermoplastic

Each of Endurance Composites' fiberglass tanks exhibit superior corrosion resistance and can be manufactured for high purity applications. When welding is required, we utilize superior welding techniques which allow for a minimum number of welds. Using only certified welders, we capitalize on the strength of the fusion methods as opposed to hand welding with hot air and filler rods. Producing welds equal in strength to the original material enables thermoforming of dished heads and flat bottoms (with knuckle radii) in one place.

Endurance Composites can manufacture straight fiberglass tanks or dual laminate tanks to a wide variety of plant specifications.

Dual Laminate Tanks

Endurance Composites has manufactured and installed dual laminate tanks and vessels for over 60 years for world-leading chemical companies such as Dow Chemical. With superior corrosion resistance, Endurance can manufacture straight fiberglass tanks or dual laminate tanks to a wide variety of planet specifications.

What is Dual Laminate?

Dual laminate is a hybrid system made of specialized thermoplastic liner inside, and fiberglass (FRP/GRP) structure outside. The thermoplastic liner can be matched to specific chemical requirements, which provides long life and the ability to withstand abrasion and high temperatures.

Why choose Endurance Composites Dual Laminate Tanks / Vessels?

Endurance has developed a proprietary bonding process which fully contact-bonds the laminates to reduce failure related to vacuum and differential coefficients of thermal expansion. This bonding process proves all other dual laminate manufacturing as old technology. With Endurance Composites dual laminate tanks, typical modes of failure do not occur due to this proprietary process.

In addition, for mechanical strength, Endurance Composites dual laminate tanks and vessels are manufactured with a fiberglass (FRP/GRP) composite matrix exterior. The corrosion resistant thermoplastic interior offers exceptional service against dangerous and hazardous chemistry. It offers superior resistance to leaching agents, chemical attack as well as high purity process capabilities.

Endurance Composites manufactures straight or dual laminate round and cylindrical storage tanks, vessels and scrubbers. Our chemical tanks can be designed for above or below ground applications. With over 60 years of expertise in the construction of fiberglass tanks, we can ship a completed storage tank to the field for installation or we can fabricate large diameter tank components in sections and sized for shipment to the job site. Our highly qualified field crews are then dispatched and can quickly assemble the components to form the completed chemical storage tank. Endurance can transport in sections or a complete tank via truck or barge.

We offer many different chemical storage tank modifications from small to larger diameter sizes. We can also provide specialized designs and construction wherever required and add whatever external hardware best suits your application.

Endurance Composites chemical storage tanks and vessels are quality engineered, designed, and built to your exact service conditions. When coupled with our Endurance straight or dual laminate piping system, you are assured of a long lasting process system solution. Our chemical storage tanks are built to meet or exceed the following standards.

ASTM D4097 (hand lay-up custom contact molded equipment)
ASTM D3299 (filament wound fabrication)
ASME Section X
