  • Composite Pipe And A Method Of Manufacturing A Composite Pipe
    Publication number: 20080087351
    Abstract: A composite pipe having at least one metal end piece (2, 3) with a free end and a non-metal tubular component (10). The tubular component (10) is coupled to the at least one end piece (2, 3) opposite of the free end of the end piece (2, 3), by means of at least one peripherally extending, axially acting groove (6, 7) that the non-metallic tubular component (10) engages. The non-metallic tubular component (10) generally comprises axial fibres (11) extending down into the at least one groove (6, 7). The groove (6, 7) has a bottom (13) and a flank (14), which flank is located furthest away from the free end of the end piece (2, 3). Between the flank (14) and the axial fibres (11) there is provided an intermediate layer (15). Also described is a method of manufacturing such a composite pipe.
