Durcor®. The World’s First Engineered Structural Composite Piping System

Durcor® features allow it to rise above competitors. Some standout features include:

• Freestanding construction: Durcor® seamless PTFE liners are designed to be freestanding (the liner is not adhered to the exterior composite housing), so you eliminate the risk of delamination present with dual laminates. 
• Lot traceability: Durcor® pipes and fittings feature a manufacture date stamp, allowing you to trace every component back to its specific lot. 
• 5-year warranty: Each Durcor® component comes with an industry-leading 5-year warranty against environmental corrosion. No steel is present except for bolts, so there is no chance for pipe corrosion under installation (CUI).
• Superior strength: Durcor® piping systems can be treated similarly as schedule 40 steel pipe, to which they are dimensionally equivalent. The difference is mainly in the torque requirements of the flanges.  Durcor® requires no more supports than steel due to similar spanning capability.  Durcor® mechanical tensile strength for a 2 inch pipe is 45,000 psi compared to 60,000 psi for steel and 14,200 psi for typical FRP piping. 
• Lightweight: Durcor® is one-quarter the weight of comparable steel piping systems, making it cheaper to transport and easier to install without scaffolding or crane systems. 
• Temperature and Pressure: Our systems easily handle full vacuum and pressures up to 275 psi and temperatures in the range of -40 F (-40 C) to 300 F (149 C). 
• Thermal expansion: Durcor® has a lower thermal expansion coefficient than steel (4.5 X 10-6 in/in/°F (8.1 mm/mm/°C) for Durcor® vs. 8.0 X 10-6 in/in/°F (14.4 mm/mm/°C) for lined steel pipe.
• Consistent ID and OD: Durcor® is made with a fully automated process with highly consistent quality ensuring consistent ID and OD.
• Flanges: Our standard offering includes rotating flanges. 
• Size range: We manufacture Durcor® piping systems in sizes ranging from 1 to 8 inches and up to 50-foot lengths to reduce the number of flange connections.
