Embodiment Construction

[0019] The technical solution of the present invention is further illustrated below through specific examples.

[0020] Further details according to the attached drawings:

[0021] The steps to connect the pipeline are as follows:

[0022] (1) Insert the PE steel wire mesh skeleton plastic composite pipe 1 into the PE electric heating sleeve 2, and connect and fix it through the metal retaining ring 3;

[0023] (2) Fluorine rubber 4 is lined at the junction of the pipes;

[0024] (3) Insert the PE plastic pipe 5 into place from the other end of the PE electric heating sleeve 2, and install the composite pipe 1 in place by means of a tensioner;

[0025] (4) Make the two ends a and b of the resistance wire of the electric melting core of the PE electric heating melting sleeve 2 energized to generate heat fusion, and realize the connection between the PE steel mesh skeleton plastic composite pipe 1 and the PE plastic pipe 5 . The connected pipeline structure is as follows fig...

Abstract

The invention discloses a connection method of a PE plastic pipe and a PE wire net skeleton plastic composite pipe, including the following steps of: (1) inserting the PE wire net skeleton plastic composite pipe into a PE electro thermal fusing sleeve; (2) inserting the PE plastic pipe from the other end of the PE electro thermal fusing sleeve; and (3) electrifying the electric melting core of the PE electro thermal fusing sleeve to generate hot melting so as to connect the PE plastic pipe and the PE wire net skeleton plastic composite pipe. By using the connecting method of the invention to connect pipes, the pipe units have safe connection and welding, and the connection intensity and tightness of the pipe material are increased greatly. The method also has the advantages of high practicality and easy generalization, therefore, pipe installation technology can be developed further and has wide application prospect.

Description

technical field [0001] The invention relates to a connection method between pipes, in particular to a connection method between a PE plastic pipe and a PE steel mesh skeleton plastic composite pipe, and belongs to the technical field of pipe connection. Background technique [0002] There are mainly two types of plastic pipes used to transport media in real life: plastic pipes and plastic composite pipes reinforced with metal skeletons. In general, PE plastic pipes are connected by hot-melt connection and electric fusion connection, and the connection with metal pipes and pipeline accessories adopts the connection method of flange or transition pipe fittings. [0003] In the prior art, the connection of PE plastic pipes by hot-melt connection and electric fusion is relatively complicated, and the safety needs to be improved. In addition, because the connection requires specific tools to complete, it has high requirements for the installation environment and is not easy to be...
