Wire rope enhanced thermoplastic composite pipe heating type buckling and pressing joint and connection method

Abstract

The invention discloses a wire rope enhanced thermoplastic composite pipe heating type buckling and pressing joint, which comprises a core pipe and an outer pipe, wherein both the core pipe and the outer pipe are L-shaped and are arranged in parallel to each other with a gap; the horizontal section of the core pipe is a core part, and the vertical section of the core pipe is an inner connecting piece; the horizontal section of the outer pipe is a buckling and pressing sleeve, and the vertical section of the outer pipe is an outer connecting piece; and an electrode which can be contacted with a wire rope enhanced layer at the end head of a composite pipe is arranged between the inner connecting piece and the outer connecting piece. The invention also discloses a connection method using thejoint. By buckling and pressing the pipe wall of the composite pipe and clamping the flanged wire rope enhanced layer of the composite pipe, double buckling and pressing effects can be realized and the connection and contact of a steel wire and the electrode are more stable. The joint has a simple structure and is convenient to connect, heat and operate; and the working efficiency and the stability and the reliability for use are greatly improved.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a heated crimping joint and a connection method of a steel wire rope reinforced thermoplastic composite pipe. Background technique [0002] Reinforced thermoplastic composite pipes are usually mainly composed of three layers, that is, inner and outer plastic layers and a reinforcing layer compounded by reinforcing materials arranged in the middle. At present, for reinforced thermoplastic composite pipes, pipes are usually connected by reinforced electrofusion sleeves, and pipes and equipment are usually connected by crimp joints or reinforced electrofusion joint flanges, so that there are various connections such as flanges and threads. form. [0003] At present, the existing technology enhances the connection method of the electrofusion sleeve. The manufacturing process of the electrofusion sleeve is complicated, and the yield and production efficiency are low. When...
