  High-density polyethylene - low price HDPE pipe

  HDPE is known for its high strength-to-density ratio. The density of HDPE can range from 930 to 970 kg/m 3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength 38 MPa versus 21 MPa than LDPE.

  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.
