Abstract
A composite pipe termination that includes: a) a composite pipe having an interior pipe surface, an exterior pipe surface, a pipe end and a liner; b) an annular portion of composite material attached to the exterior pipe surface, the annular portion having a first stepped region in which the annular portion decreases in radial thickness in the axial direction away from the pipe end by at least one step; c) an annular collar enclosing the first stepped region; d) an end-fitting interfacing with the annular portion and locked to the annular collar. The annular collar has a stepped portion in which the annular collar increases in radial thickness in the axial direction away from the pipe end by the same number of steps as in the first stepped region. The steps of the stepped portion mate with steps of the first stepped region.
