Abstract: The present invention discloses redundant sealing systems for composite risers having metal liner assemblies and methods of preventing interior fluid leakage to the outside of composite risers. An elastomeric seal is formed between an elastomeric tip provided on the end of a metal to composite interface (MCI) of the liner assembly and an elastomeric shear ply provided over the liner assembly. The elastomeric seal and a mechanical seal between the MCI and a transition ring which secures the liner to the MCI, provides a dual sealing system for the composite riser to prevent leakage of interior fluids. In the event that the integrity of the mechanical seal or the integrity of the liner is compromised, the elastomeric seal would prevent leakage of the fluid to the outside of the composite riser.

Abstract: The present invention discloses multiple sealing systems for composite risers and methods of preventing interior fluid leakage to the outside of composite risers. Single or multiple elastomeric seals are formed between an elastomer applied in single or multiple grooves provided circumferentially along the outer surface of a metal to composite interface (MCI) of a liner assembly of the composite riser and an elastomeric shear ply provided on the outside of the liner assembly. The elastomeric seals and a seal between the MCI and the liner of the liner assembly provide a multiple sealing system for the composite riser to prevent leakage of interior fluids. In the event that the integrity of the seal between the MCI and liner fails or the integrity of the liner is compromised, the elastomeric seals would prevent leakage of the fluid to the outside of the composite riser.

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 fibers (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 fibers (11) there is provided an intermediate layer (15). Also described is a method of manufacturing such a composite pipe.
