FRP pipe systems that are designed to meet rigid specifications should be tested to prove that they will perform accordingly. FRP pipe systems are used for severe corrosive and erosive process streams and customers need peace of mind in knowing their design has been properly validated. ASME B31.1 “Power Piping” references ASTM D6041 that is a standard specification for contact molded pipe and fittings, and includes requirements for materials, design, and proof testing. Testing a typical fitting such as an elbow or reducer would involve pressure testing with ambient temperature water to four times the rated pressure for one hour without leakage. This paper will review what is required by ASTM D6041 as well as give an overview of a recent program to develop and proof test 290 psi (20 Bar) pipe, fittings, flanges, and laminated joints.
