    The nature of polyethylene pipe failure |

    18/1/2011· 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
