Fiberglass Pipe

Fiberglass Reinforced Pipes

Quality Fiberglass (FRP/GRP) pipe requires extensive experience, knowledge, and training working with resin complexities. Endurance has produced fiberglass pipe for world class companies like Dow Chemical for over 60 years. With our ability to manufacture, fabricate, and install FRP pipe and fittings, we ensure even the most complex projects will be successful.

Endurance produces fiberglass pipe from 1" to 72" in diameter, and we source virtually any resin required for your application. Our FRP pipe can meet or exceed a multitude of plant specifications, pressure ratings, and industry standards.

We utilize hand lay-up techniques and filament winding in our manufacturing process. The difference in these techniques is the orientation and layering of the glass fibers. The below diagrams show hand lay-up utilizes woven glass rovings as opposed to continuous glass rovings.

Dual Laminate Pipes


Endurance brand of dual laminate pipe is designed to meet or exceed a multitude of plant specifications and various pressure ratings as well as industry accepted standards. Having manufactured pipe for world class companies like Dow Chemical for over 60 years, Endurance dual laminate pipe can be manufactured from 1" to 72" with a complete line of fittings.

What is FRP Dual Laminate?

  • Dual laminate is a hybrid system made of fiberglass (FRP/GRP) structure outside and specialized thermoplastic or fluoropolymer liner inside. The liner is matched to specific chemical requirements to optimize longevity including the ability to withstand high temperature requirements or abrasion resistance.

Why Choose Endurance Dual Laminate Pipe?

The key to Endurance Composite's high quality dual laminate pipe is a proprietary bonding procedure which overcomes the common mode of failure in other dual laminate pipe. Our process fully contact-bonds these laminates to reduce failures related to vacuum and differential coefficients of thermal expansion. This innovative method makes all other dual laminate manufacturing processes old technology.

Endurance Composites dual laminate pipe is also manufactured with a durable fiberglass (FRP/GRP) composite matrix exterior for mechanical strength. The corrosion resistant thermoplastic or fluoropolymer 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.
