  • Patent number: 6634387
    Abstract: A reinforced flexible tubular pipe including an inner liner (3) that forms a barrier against outflow of medium that flows through the pipe, the inner liner (3) being encased by at least one reinforcing layer having a space in which a number of profiles are configured that are coiled around the inner liner such that the profiles are completely or partially surrounded by a lumen (10) that allows transport of fluids in the longitudinal direction of the pipe. Outside the reinforcing layer an outer coating (9) is provided to form a barrier against inflow of fluids or gases from the surroundings of the pipe to the reinforcing layer. At least one flow path (11) is provided to convey fluid or gas away from the lumen (10). This flow path (11) is provided with an inlet opening that debouches in the lumen (10) and an outlet opening (13) that ends in the inner liner of the tubular pipe.

  • Patent number: 6360781
    Abstract: An assembly of an end-fitting (9), having an axial extending through opening (14), with a flexible pressure pipe (1) which is of a non-bonded structure comprising a number of layers (2, 3, 4, 5, 7) including an inner carcass (2) of an interlocking structure made from metallic strips (23) forming a screwthread, an end part of which extends, in the assembled condition, into the through opening (14). The assembly comprises an annular holding groove (28) which is formed in the wall of the through opening (14), and a lock nut (15). The metallic strips (23) form a thread (24) with windings (25). When the pipe (1) is to be assembled with the end-fitting (9) the carcass (2) is exposed by initially removing the layers (3, 4, 5, 7) surrounding the carcass (2) at the end of the pipe (1), whereafter the lock nut (15) is screwed on to the end of the carcass.
