Abstract:
1. A method for joining pipe sections in pipe system for containing corrosive petroleum products, the system comprising at least two separate pipe sections, a first pipe section and a second pipe section, the method comprising: positioning the first pipe section adjacent to the second pipe section, each pipe section comprising a structural layer comprising a composite material and a corrosion resistant layer for contacting the corrosive petroleum product, and a fire resistive layer; applying energy to join the corrosion resistant layers of the first and second pipe sections together forming a joint; applying an external wrap around the joint of the first and second pipe sections; bonding the external wrap to the joint and the composite structural layers by at least one of chemical curing and thermal treatment; and covering the external wrap with a layer of fire resistive material.
