Title:
COMPOSITE PIPE ASSEMBLY AND METHOD FOR ITS PREPARATION
Document Type and Number:
WIPO Patent Application WO2001098701
Kind Code:
A9
Abstract:
A composite pipe assembly comprises a pipe (4), a housing (6) comprising a tubular portion (8), said tubular portion being disposed around the outside of the pipe (4), and a tubular forge member (10) having an outer surface. The forge member is disposed within the housing whereby a portion of the pipe wall (5) 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, and the tubular portion of the housing is thereby deformed radially outwards. 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.
