JOINT FOR THERMOPLASTIC PIPE, ASSEMBLY AND METHOD

摘要

A pipe joint includes: a coupling including a tubular wall with an outer surface and an inner surface defining an inner diameter; an end of a first pipe in the inner diameter of the coupling with an outer facing surface of the first pipe adjacent the inner surface; an end of a second pipe in the inner diameter of the coupling with an outer facing surface of the second pipe adjacent the inner surface, the end of the first pipe and the end of the second pipe arranged in an end-to-end scarf joint configuration and a seal between the end of the first pipe and the end of the second pipe; a thermoplastic weld between the coupling inner surface and the outer facing surface of the first pipe and the coupling inner surface and the outer facing surface of the second pipe; and a first plurality of fasteners installed substantially radially inwardly from the outer surface of the coupling and engaging the coupling and a fiber reinforced layer of the first pipe and a second plurality of fasteners installed to extend substantially radially inwardly from the outer surface of the coupling and in engagement with the coupling and a fiber reinforced layer of the second pipe.
