    During the 1995 Kobe Earthquake in Japan, the HDPE water networks were the only pipe networks that survived with less than 0.002% loss of network integrity. In contrast, over 78% of the rigid pipeline sections failed causing widespread drinking water and pressure loss for firefighters trying to cope with over 300 fires caused by broken gas lines across the city.

    The nature of polyethylene pipe failure | plasticstoday

    17/11/· Early 1960''s research of HDPE pipes established three major failure modes for PE pipe: ductile failure (mode I), brittle failure (mode II) and brittle/chemical failure (mode III). Ductile failure was associated with yielding and reflected a material''s propensity to undergo large-scale, irreversible ''plastic'' deformation when under stress, the yield stress describing the load intensity at which Puhui Pipe manufacturer in China

    In this paper, we chose HDPE pipes as material for our study. Then, we leaded a new approach of failure analysis and prediction using new models. These models are obtained through a modified version of the stress controlled unified theory, a static damage model using burst pressures and a static damage model using the time to failure.
