Abstract
A composite pipe assembly comprises a pipe having a pipe wall, a housing comprising a tubular portion having an inner surface, said tubular portion being disposed around the outside of the pipe, and a tubular forge member having an outer surface. The forge member is disposed within the housing whereby a portion of the pipe wall is disposed between the inner surface of the tubular portion of the housing and the outer surface of said forge member. The forge member is deformed radially outwards against the pipe and the housing, preferably to beyond its yield point, and the tubular portion of the housing is thereby deformed radially outwards to a partial yield point. As a result, the tubular portion of the housing applies a compressive force radially inwards against the pipe wall and the forge member applies a force radially outwards against the pipe wall which serves to secure the housing to the pipe and provide a seal between the pipe and the inner surface of the tubular portion of the housing. The assembly is useful for providing an end fitting to a composite pipe, providing a repair to a section of damaged pipe, or providing a joint between two sections of pipe. The forge member an…
