ASTM D2997 PDF

FRP is a composite material consisting of thermoset resin and a fiber reinforcement. There are many types of resins and reinforcements and each imparts specific properties to the final product. Some of the resins include Polyester, Epoxy or Phenolic resin. Glass Fiber "E-glass" is the most widely used reinforcement.

Pipes can be manufactured by contact moulding hand lay-up or hand lay-up in combination with filament winding. They are manufactured from glass or synthetic fibres such as polyester. The surface veil is generally the innermost layer in contact with the process fluid. Piping designed for pressure service are generally designed to a safety factor of The safety factor takes into account the loss of strength of the laminate under continuous long term load and loss of strength due to corrosion effects of process fluid.

For corrosive process fluids, a resin rich layer is provided on the innermost layer. Typically a corrosion barrier may consist of the following. Antimony Trioxide or brominated compounds are added to provide excellent fire resistant characteristics to FRP.

FRP piping - Introduction

Historical Version s - view previous versions of standard. More D This specification covers machine-made glass-fiber-reinforced thermosetting-resin pressure pipe manufactured by the centrifugal casting process. Pipe covered by this specification has been found suitable for conveying gases, petroleum products, or corrosive fluids. For the purposes of this standard, polymer does not include natural polymers. Pipe meeting this specification shall be categorized by the prescribed long-term static or cyclic hydrostatic design basis when tested.
