The first PE pipe material used in engineering appliions was Type 50 High Density PE HDPE with a long term stress of 50MPa. Subsequently, Medium Density MDPE materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.
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.

Thermal conductivity W/mK development has led to reduction in the length of pipes as well as improved heat pump performance [13,57]. Pasquier et al. [58] tested the thermal performance of Puhui Pipe manufacturer in China
Hdpe Pipes & Fittings Description: HDPE welding is a form of plastic welding commonly used in pluing and underground piping to join lengths of pipe together. A quick and simple process, HDPE welding simply involves heating HDPE to the correct temperature and then fusing it together with another piece.
9-1 1--2-91 P J 01, 201 MADE IN U.S.A. P IMPORTANT INFORMATION High density polyethylene pipe HDPE has several properties that make it very different from “tradi-tional” water works pipe materials: • Coefficient of thermal expansion is over 10 times
