Abstract

The invention provides a hot-melt connection method of a pipeline connecting piece. The hot-melt connection method of the pipeline connecting piece has the beneficial effects that the pipeline connecting piece and a pipeline are connected in a hot-melt mode, the use quantity of bolts is reduced, and operation efficiency is improved; in this way, when a heated pipe piece and a melted block are connected, the melted block seals the portion surrounding the pipe piece in a fused mode, the pipe piece connecting effect is better, and connection is more convenient.

Description

technical field [0001] The invention relates to a pipe connection method, in particular to a heat-melt connection method for pipe connectors and the connectors using the method. Background technique [0002] With the rapid development of the modern international petrochemical industry, the pipeline system has also developed from the traditional metal pipeline to today's plastic pipeline system and metal-plastic composite pipeline system, which has greatly improved the scope and quality of pipeline applications. Since the 1980s, thermoplastic organic polymer materials such as polyethylene plastics, polypropylene plastics, and polybutene plastics have been successfully used in piping systems. Such pipes mainly include thermoplastic pipes and metal-lined plastic composite pipes. The structure of the metal-lined plastic composite pipe is a thermoplastic pipe in the inner layer and a metal layer wrapped around the plastic pipe. This type of pipeline system is connected with pip...
