Abstract

A method for the connection between two large-diameter composite metal-plastic pipes includes such steps as moving them closely while aligning them for butt connection, and adhering a splicing layer on the external surface of both ends to be connected for cladding them. Its advantages include easily making said splicing block layer composed of splicing units, easy operation and high connection reliability.

Description

technical field

[0001] The invention relates to a method for connecting pipes, in particular to a method for connecting large-diameter metal-plastic composite pipes. Background technique

[0002] At present, metal-plastic composite pipes have been widely used in many fields, and the accompanying new technology of pipe connection has also emerged. In the specific implementation, the connection of small-diameter pipes uses heating tools to make the pipes and fittings to be connected hot-melt and then implement socket connection. It is feasible, and the melted plastic after heating can fill the gap between pipes and pipe fittings and achieve sealing. In addition, the dimensional deviation between small-diameter pipes and pipe fittings can also be controlled within the range allowed by the hot-melt socket technology. However, when the diameter of the pipe increases, due to the increase in volume and weight of the pipe and pipe fittings, it is not only impossible to implement t...
