Product Features & Benefits

  • STRAIGHT FIBERGLASS TANKS OR DUAL LAMINATE TANKS: Endurance™ Composites can manufacture straight fiberglass tanks or dual laminate tanks to a wide variety of plant specifications.
  • SUPERIOR CORROSION RESISTANCE: Each Endurance™ Composites fiberglass tank exhibits superior corrosion resistance and can be manufactured for high purity applications.
  • EXCELLENT WELDING TECHNIQUES: 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.
  • DESIGNED FOR ABOVE OR BELOW GROUND APPLICATONS: Our chemical tanks can be designed for above or below ground applications. We can ship a completed storage tank to the field for installation or fabricate large diameter tank components in sections and sized for shipment to the job site. Our highly qualified field crews can quickly assemble the components to form the completed chemical storage tank. Sections or a complete tank can be transported via truck or barge.
  • SPECIALIZED DESIGNS AND CONSTRUCTIONS AVAILABLE: Endurance™ Composites will provide specialized designs and construction if required, and add whatever external hardware best suits your application.
  • QUALITY ENGINEERED, DESIGNED, AND BUILT: 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
