Hdpe tank temperature limit

WebThe temperature change experienced = 48 – 18 = 30°C. The thermal movement rate (Figure 4.5) in mm/m for 30°C= 6.0 mm/m. The total thermal movement is then 6.0 x 100 = 600 mm. Where pipes are buried, the changes in temperature are small and slow acting, and the amount of expansion/contraction of the PE pipe is relatively small. HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m . The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1 (MVS2PRO density analyzer). 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 diff…
