Background

The thermal winding pipe is a new type special-shaped structure wall pipe, and is made up by adopting high-density polyethylene or polypropylene thermal winding forming process. The product takes high density polyethylene resin (HDPE) or polypropylene as a raw material, takes a PP corrugated pipe as an auxiliary supporting pipe, and adopts a hot winding forming process to produce the high density polyethylene or polypropylene large-caliber winding reinforced pipe. The pipe is originally introduced from German Clar company by domestic companies, so that the pipe is commonly called as Clar pipe in China, and the novel light pipe made of high-density polyethylene or polypropylene has the characteristics of light weight, high pressure resistance, good toughness, fast construction, long service life and the like.

As the pipe is usually buried in underground water drainage and bears the external pressure, the performance of the pipe is directly influenced, the measurement index is the ring stiffness, and if the ring stiffness of the pipe is not enough, the pipe can be deformed due to the fact that the pipe cannot bear the external pressure in construction or action. Therefore, how to improve the impact strength of the pipe and improve the ring stiffness of the pipe are problems that need to be solved by those skilled in the art.
