While there have been lab and field studies on HDPE pipe, a review by Stern and Lagos points out the complexity of risk assessment of plastic water pipes (14). Which chemicals migrate from any given pipe depend not only on chemical formulation, but also on pipe material characteristics, and possibly even the surrounding ground or fill material around the installed pipe.

HDPE Pipe & Fittings High density polyethylene (often called alkathene or polythene) has been used since the early 1960s. It is suitable for both potable water and wastewater services but it can only be used for cold water supply. It is the most commonly used Puhui Pipe manufacturer in China
HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or HDPE mains pipelines. Made from the thermoplastic HDPE (high density polyethylene), its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines. Puhui Pipe manufacturer in China
Figure 3: Infrared reflection spectra of HDPE after 5 weeks in 60 C water with and without 5 ppm chlorine. At the 3 rd and 5 th week of immersion at 60 o C water, the commercial pipe sample showed no appreciable surface formation of the carbonyl functionality.
HDPE pipe material in its normal form where the elongation to break can be from 600 1000%. Technical publiions have documented that oxidative degradation of polyethylene pipe can lead to premature failure of the pipe [16 20] and that HDPE pipe used
Plastic Water Pipe indies that the average flow velocity for normal flow is 6.7 ft/s ( 2 m/s) and for fire flow is 11.6 ft/s ( 3.5 m/s). The AWWA Water Distribution Operator Training Handbook suggests 5 ft/s (1.5 m/s) as a typical
In use in potable water appliions since the 1970s, high density polyethylene (HDPE) pipe has become the ideal material for piping systems used to transport drinking water. As a tough and resilient material capable of lasting 100 years or more with minimal maintenance, HDPE pipe has proven to be superior to many other piping materials as a means transporting and distributing potable water.
