Abstract
A structural component for use in oil, gas, exploration, refining and petrochemical applications in the form of a pipe system is provided. The pipe system contains at least two pipe sections are that fusion bonded together, each pipe section comprises a plurality of layers, an inner layer in contact with the corrosive petroleum product comprising a thermoplastic material, a structural layer comprising a composite material, and an outer layer comprising a fire resistive material. In one embodiment, the pipe system meets level II fire endurance standard according to IMO A 18/Res.753 fire testing protocol.
Claims26
