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.

Structural components for oil, gas, exploration, refining and petrochemical applications

A method to form a pipe system which meets level II fire endurance standard according to IMO A 18/Res.753 fire testing protocol, for use in oil, gas, exploration, refining and petrochemical applications is provided. In the pipe system, 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. The method comprises applying energy to join the corrosion resistant layers of the separate pipe sections together forming a joint, applying an external wrap around the joint and at least a portion of the composite structural layers of the at least two pipe sections, and bonding the external wrap to the joint and the composite structural layers by chemical curing, thermal treatment, or combinations thereof.

Methods for joining pipe section in a pipe system containing corrosive petroleum products

A method to improve corrosion, abrasion, and fire resistant properties of structural components for use in oil, gas, exploration, refining and petrochemical applications is provided. The structural component is suitable for as refinery and/or petrochemical process equipment and piping, include but are not limited to process vessels, transfer lines and process pipes, heat exchangers, cyclones, and distillation columns. The method comprises providing the structural component with a plurality of layers, a corrosion resistant layer in contact with the corrosive petroleum products comprising a material selected from amorphous metals, ceramic materials, or combinations thereof; a structural layer; and an outer layer comprising a fire resistive material. In one embodiment, the structural component is further provided with at least another layer selected from a metal sheeting layer, an adhesive layer, and a containment layer. The structural component is characterized as having excellent corrosion/abrasion/erosion properties and fire-resistant properties.
