[0002] PE pipes have good corrosion resistance and can resist erosion by a variety of chemical media. They have a long service life in the soil. During installation, hot-melt tools are required to fix them and heat the ends of the PE pipes to a molten state. Then the two pipe ends are quickly connected together to form a solid connection after cooling. This connection method has high strength and can withstand high pressure and tension.
