    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 such effects occur.

    Gas Distribution FAQ | Chevron Phillips Chemical

    For example, in a typical 8" line, a velocity change of 5 fps would cause a 51 psi surge in HDPE DR17 pipe, a 87 psi surge in PVC DR18 pipe, and a 262 psi surge in DI Class 350 lined pipe. Lower surge pressures often mean longer life for pumps and valves in an HDPE pipeline, as well as lower pressure class pipes.
