Background

With the increasing of the investment of the country on the infrastructure, the construction of the water supply pipeline is also accelerated, the variety and the specification of the pipe are rich, and the yield is increased. In recent years, polyethylene pipes (PE pipes) have been developed rapidly in our country, and their market share is beginning to lead other plastic water pipe materials due to their excellent properties. The PE pipe has the advantages of long service life, good corrosion resistance, convenient construction, excellent flexibility, good scratch resistance and the like. In addition, the high performance price ratio of the composite pipe enables the composite pipe to stand out from various water delivery pipes, the development is very rapid in short years, and the application is very wide.

The water flow in the water supply pipe can generate a pulling force on the wall of the water supply pipe in the same direction as the water flow. Especially, the main water pipe of the water supply pipe network is provided with large internal water volume and flow velocity, so that the borne pulling force is larger, the wall of the water supply pipe generates the pulling stress opposite to the water flow direction under the action of the water flow pulling force, and the water supply pipe is easy to be subjected to over-negative aging and fracture under the action of the pulling stress for a long time.
