In the past decade, fiberglass reinforced plastic (FRP) has emerged as a significant linepipe material and we are beginning to harness the technology and "know-how" for its successful use. FRP can be the answer to our need for low cost corrosion resistant linepipe materials due to the increasing corrosivity of produced fluids from existing fields, and newly developed aggressive reservoirs. The experience of Exxon Co. U.S.A. and Esso Resources Canada Limited with FRP linepipe has been good in mild to moderate service environments by derating manufacturers' claimed performance; however, failures have been encountered mostly due to mechanical damage and product inconsistencies. Emerging API specifications(a) should provide realistic pressure ratings, facilitate purchasing and enhance the quality of products. In more aggressive environments, significant improvement in engineering and design may be required. Additional opportunities for FRP linepipe are described.
