Problems solved by technology

The method of the present invention can effectively and satisfactorily solve the problem of being the weakest link most easily torn due to the exposure of the fusion ring seam between the electrothermal fusion pipe connector and the connected pipe section to the medium in the pipe when the traditional connection method is adopted , greatly improving its connection strength, and is conducive to giving full play to the ability of the electrothermal fusion pipe connector to withstand internal pressure blasting force and axial tension

Embodiment Construction

[0012] figure 1 What is shown is a structural representation when the above connection method of the present invention is directly used. Put the electric heating wire 5 on the inner wall electric heating wire 5, and the electric heating melting pipe connector 1 set on the outer wall, which is also provided with a metal reinforced structural layer 2, and place it in the wall layer with organic silk, mesh and other reinforcing layers. Outside the plastic pipe section 3, the relative connection ports 4 of the two pipe sections 3 are first connected to each other with an electric melting machine and connected by electric melting to form an integral structure, and then the above-mentioned electric melting pipe connector 1 is sleeved on the port On the outside of the tube wall at the melting point, the electric heating wire 5 is energized to make it and the outer wall of the tube at the melting point also be electrothermally welded to each other to complete the entire connection.

Abstract

A method for joining two medium-pressure composite plastic pipes includes such steps as butt connecting the ends of two pipes to be joined, electrosmelting joining them into a whole, sleeving an electrosmelting sleeve pipe round the joined position, and electrosmelting for reinforcing purpose. Its advantage is high join strength.

Description

technical field [0001] The invention relates to a method for connecting medium-pressure composite plastic pipes with reinforced structures in pipe wall layers. Background technique [0002] Plastic pipes based on polyethylene, polypropylene, etc. have the characteristics of light weight and corrosion resistance, and have been widely used in industrial and civil fields. In order to solve the weakness of low impact resistance and compressive strength of a single plastic material pipe, and improve its compressive and tensile strength, organic fiber silk layers or mesh layers such as aramid fiber and polyester are added to the wall layer to strengthen the structural layer , or composite forms of plastic pipes and tubing with metal reinforcement layers in the form of wire, mesh or sheet metal are increasingly used. When these pipelines are connected at present, it is all carried out by pipeline connectors that can cooperate with it and have electric heating wires and other elect...
