PE pipes have the advantages of long service life, good corrosion resistance, convenient construction, excellent flexibility, good scratch resistance, etc. In addition, their excellent cost performance makes them stand out from various water pipes. In just a few years, they have developed very rapidly and are widely used.

[0003] In the process of producing PE pipes, after the PE pipes are formed by injection molding and extrusion, the pipes need to be quickly cooled and shaped to avoid deformation of the pipes, which will affect the appearance and cause quality problems.
