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
2/3/2010· The minimum yield strength is the key property of HDPE used in pipeline design. See Figure 11.10.This figure shows the relationship between stress and strain. The minimum yield strength is defined as the tensile stress required to produce a total elongation of 0.5%.
The MPCA requires a minimum thickness of 40 mil for HDPE liners. For exposed HDPE liners 100 mil is required (see Puhui Pipe manufacturer in China Break Strength (lb/in) 152 150 Yield elongation 12% 12% Break elongation 700% 100% Tear resistance (lb) D1004 28 70 D4833 300 2.0 Puhui Pipe manufacturer in China
Pipe resins Our lineup of HDPE pipe resins starts with CONTINUUM™ Bimodal Polyethylene Resins and INTREPID™ Bimodal Polyethylene Resins. They offer smart options for improved service life, safety and sustainability by producing extremely durable, leak- and corrosion-resistant, flexible pipe.

Where DI pipe has a yield strength of 42,000 psi in such regards, HDPE has a design limit of 1600 psi in material yield resistance, prior to safety factors being applied for either service allowance and casting tolerance in the pipe walls as produced.
4 Only PE materials with a cell classifiion of 445474C (or higher) per ASTM 3350-05 (or PE 4710 material per the Plastic Pipe Institute designation) are permitted to be used for Class 3 piping. The interpretation of the above cell classifiion is shown in Table 1
Polyethylene is a whitish, semi-crystalline, and effectively opaque engineering thermoplastic which, chemically, is a very high molecular weight (3-6 million) HDPE. As a result, its melt viscosity is extremely high and normally can only be processed by powder Puhui Pipe manufacturer in China

20/1/2003· According to Bond,5 the tensile strength of HDPE pressure pipe material is shown to decrease from 21 MPa at 23uC to 10 MPa at 60uC. Other …
The HDPE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers (Q&A''s) of all the elements through the pipe system value chain: design, materials, construction
Hdpe Pipe (High Density Polyethylene Pipe) is hard, light, solid pipe with a smooth inner and outer surface. Transportation of HDPE Pipe requires minimum equipment and is easily applied in all field conditions, on ice or in wet floor, marshy areas.
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.
