Pipe network for connecting holed metal skeleton reinforced plastic composite pipe and plastic connector

Abstract

A tube network is composed of the perforated metallic skeleton reinforced composite plastic tubes and the plastic connecting tubes. Said composite plastic tube is formed by wrapping the perforated skeleton by plastics and consists of skeleton, internal plastic layer and external plastic layer. Said plastic connecting tube has at least one stepped socket end for connecting one end of said composite plastic tube by thermal fusion.

Description

Technical field:

[0001] The invention is related to the connection of plastic pipes, steel-plastic composite pipes and plastic pipe fittings, especially the connection technology for connecting plastic composite pipes and plastic pipe fittings reinforced by metal skeletons with holes to form a pipe network through thermal fusion. Background technique:

[0002] The connection between the known metal-composite plastic pipes and plastic pipes is connected by mechanical clamping method, and the electric heating wire distributed in the inner cavity of the socket of the pipe fitting is used. Fusion connection, there is a method of using hot-melt socket fusion connection between pure plastic pipes and plastic pipe fittings, but most of them are connected with small diameters, such as: pure plastic pipes less than φ110, and there are also unpublished methods that the author has applied for. The method of friction heat fusion connection, the method of heat melting the conical surface...
