High density polyethylene (HDPE) has been used for municipal and industrial water applications for almost 50 years. HDPE's heat-fused joints create a leak free, self restraint, monolithic pipe structure that allows the pipe to be pulled from one area to another with minimum disruption to traffic or the environment; the fused joint will also eliminate infiltration into the pipe and exfiltration into the environment. HDPE has other benefits which include chemical, abrasion, fatigue, seismic and corrosion resistance.
HDPE has been used in drinking water pipe applications for almost 50 years and has been gaining approval and growth in municipalities ever since. HDPE is specified and/or approved in AWWA C901, AWWA C906, NSF 14, NSF 61 and ASTM International D3035. Also, HDPE has been is use for sewer pipe applications for more than 30 years. Independent testing of HDPE in sewer service for 25 years showed no significant changes in the material's physical or chemical properties. Also, HDPE's unique characteristics have made it the product of choice for numerous mining pipe applications. It is a proven product in rugged terrains, extreme climates and changing site environments. HDPE is also preferred in industrial pipe applications because the hazardous nature of some chemicals being transported in industrial pipe applications is protected by HDPE's fused joint.
