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.
Fibef Reinforced Plastic (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 our recent program to develop and proof test 290 psi (20 Bar) pipe fittings flanges and laminated joints.- Tony Zacharewych P.Eng

Fiberglass reinforced plastic (FRP) has properties that, if disregarded, can lead to failure during operation. The same properties, if taken advantage of, can provide the user with performance superior to traditional alloy materials. This paper discusses principles in designing process and facilities piping systems with FRP.
