that the long term durability of PE pressure pipe is dependent upon its resistance to inhibit the initiation and slow growth of cracks. This failure mechanism can also occur in all types of fusion joints. Early research of HDPE pipes established that SCG was one4.

HDPE pipe''s durability is demonstrated by this highway cross drain installed in 1981 near an abandoned strip mine. The metal pipe used prior to this time had to be replaced every few years due to the highly acidic (pH range was between 2.5 to 4.0) and abrasive Puhui Pipe manufacturer in China

Plastic pipes, such as Polyethylene Pipe (HDPE) used in landfills and storm sewers and PVC pipe in sanitary sewers, are often susceptible to deflection. Pipe deflection is a significant source of delays and cost overruns in sewer projects, while, in landfills, deflection can force operators out of EPA compliance and potentially cost millions of dollars to correct.
