    Is High-density Polyethylene HDPE a Good Choice

    High-Density Polyethylene HDPE pipe has been used for decades in non-potable water appliions. In particular, HDPE pipes are often preferred for their welded joints [2] . While special equipment is required to form the weld, welding eliminates the need for separate fittings, a common source of leaks and contaminant infiltration.
