Fiberglass-reinforced plastic (FRP) pipe is a composite material using a polymer matrix reinforced with fiberglass. The composite consists of fibers or fabric for structural strength, saturated in various types of resins, such as thermosetting polyester, epoxy, phenolic resin, and others, chosen to give the pipe the properties needed.

FRP pipe is available in sizes from 1- to 144-inch and offers many ideal characteristics. It is non-conductive to electricity, corrosion and abrasion resistant, and non-toxic. It has a low coefficient of friction (more than 25% better than steel pipe), is dimensionally stable, and lighter than steel with a higher strength to weight ratio. Several joining techniques can be used for installations both above and below ground.

FRP can be used in virtually any piping application except where high temperatures (above 100°C) exist. Common uses include fume scrubbers, hood and ventwork, process piping, oil field gathering lines to sewer and water mains in the municipal and industrial markets. It can degrade from exposure to UV rays, although the degradation can be diminished using various UV stabilizers in the resin. FRP conforms and numerous ASME/ANSI, ASTM, and AWWA standards. *
