    HDPE pipe - low price HDPE pipe

    HDPE pipe is very durable and flexible and can be bent on site to a radius twenty-five times the nominal pipe diameter - for SDR11 and SDR17 pipe, at or below 20 C aient temperature. This provides major cost savings, when compared to different pipe systems, some of which require glued fittings, restraints or thrust blocks for even minor changes in direction.

    The nature of polyethylene pipe failure | plasticstoday

    16/11/· 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
