Joints 

High-density polyethylene (HDPE) pipe has been used for municipal and industrial water applications for about 50 years. HDPE’s heat-fused joints create a leak-free, self-restraint, monolithic pipe structure. The fused joint will eliminate infiltration into the pipe and exfiltration into the environment

One of the greatest features of HDPE pipes is the fact that a wide variety of jointing systems is available to suit a whole range of applications. The jointing systems can be divided into permanent jointing and detachable jointing. The schematic below illustrates the available systems.
