Single Wall FRP Pipe

Conley single wall pipe fabrication


Conley Composites single wall fillament wound fiberglass reinforced pipe and fittings are engineered to the highest, most exacting standards in the industry. Painstakingly manufactured with a triple layered approach to fight corrosion, there's simply no better or more reliable FRP pipe on the market.

Conley products all begin with Premium epoxy or vinyl ester resins in its exlusive three stage process:

  • (Stage 1) We add multiple layers of Nexus synthetic veil reinforcement saturated with aromatic amine cured premium epoxy, vinyl ester or Furan resin for a rich corrosion barrier. Our resin rich liner is 90% resin and 10% veil reinforcement for a combination of superior chemical resistance and impact resistance.
  • (Stage 2) Over the resin rich liner is an aromatic amine cured epoxy filament wound reinforced wall of multi - layered continuous glass delivered under controlled tension for optimum hoop and axial strength.
  • (Stage 3) In the last stage, epoxy resin rich Nexus layers are added to the exterior to provide maximum corrosion resistance, impact resistance and aids to elminate fiber blooming caused by the damaging effects of ultraviolet (UV) exposure. No other composite pipe/fitting manufacturer offers the benfits of a Conley piping system.


Available in a broad range of sizes from 1"-30", Conley FRP pipe and fittings are the perfect solution for hot pickling acid (HCl) lines in steel mills, as well as other acids, caustics, various waste solutions, brines and a wide range of solvents. Backed by a 25 year guarantee against fiber blooming, you can trust Conley FRP Pipe and Fittings to perform day in and day out as a vital part of your process system.



Pipe resin

We offer four unique resin types for the internal and external protection of your piping system. Whatever resin you choose

Epoxy Fiberglass Pipe

Conley Aromatic amine cured epoxy resin systems perform best in caustics, brines, solvents and many acids up to an operating temperature of 275°F (Conductive system available). E-plus, Conley's proprietary premium epoxy has outstanding chemical resistance 98% sulfuric acid and aggressive solvents such as acetone, chloroform and methylene choloride up to an opterating temperature of 275°F. See chemical resistance guide for more information.

Epoxy Systems

For more than a half century, Conley’s Epoxy Piping Systems have exceeded expectations and in many cases out performed the competition due the 3 layer composition & aromatic amine curing system. Our Epoxy Systems perform well in a broad base of chemical environments, and exceptionally well in high temperatures (Up to 95̊°C) of steel pickling lines, as well as other steel mill applications with much lower cost than lined pipe or exotic metals

Unlike many other FRP piping systems, there is no glass in the external corrosion barrier. Reduced lung, eye, and skin irritation from airborne glass particulates commonly associated with preparation for joining.

All Conley Piping System components are oven post-cured for superior chemical resistance and HDT (Maximum temperature performance).
