HIGH PRESSURE PIPE COUPLING CONSTRUCTION, AS WELL AS METHOD FOR FORMING SAID COUPLING CONSTRUCTION

摘要

A high pressure pipe coupling construction includes at least one high pressure pipe (2) as well as a coupling (22) connected to the pipe (2). The pipe consists a reinforcement layer (4) of helically arranged fibers (6, 7) and the coupling (22) consists an inner sleeve (23) sealed with respect to the inner surface of the pipe and at least one metal outer sleeve (9). The metal outer sleeve (9) has an overlapping outer sleeve part (29) overlapping the inner sleeve (23) in axial direction and a protruding outer sleeve part (25) protruding in axial direction with respect to the inner sleeve (23), which overlapping outer sleeve part (29) and protruding outer sleeve part (25) are connected to the outer surface of the pipe (2). The inner sleeve (23) consists of a plastic material; at the location of overlap between the inner sleeve (23) and the pipe (2), the maximum outer diameter of the inner sleeve (23) is smaller than or equal to the minimum inner diameter of the pipe (2).

1. High pressure pipe coupling construction, comprising a high pressure pipe (2) as well as a coupling (22) connected to the pipe (1, 2) at a pipe end thereof, said pipe comprising a reinforcement layer (4) of helically arranged fibers (6, 7), said coupling (22) comprising a non-metallic inner sleeve (23) sealed with respect to the inner surface of the pipe and a metallic outer sleeve (9) connected to the outer surface of the pipe, and a metallic force transfer fitting (15) beyond the pipe end, which force transfer fitting (15) is connected to said outer sleeve (9) and to a mounting means (20) located at the end of the force transfer fitting (15) which faces away from the outer sleeve (9), wherein the non-metallic inner sleeve (23) extends through the metallic force transfer fitting (15) and through the mounting means (20) and has a seal fitting (32) at the end of the mounting means (20) which faces away from the pipe (2).
