The HDPE Pipe Jointing Project is a process in which the two ends of the pipes to be heated and welded by using a butt welding machine and the both ends are pushed toward each other by pressure under a certain temperature. HDPE pipe is a flexible plastic pipe made of thermoplastic high-density polyethylene widely used for low-temperature fluid and gas transfer. The material is joined by butt welding, electrofusion welding or extrusion welding. HDPE Pipe Jointing Project is very useful.
