The rate of thermal expansion usually depends on three key factors: The pipe material – different materials expand at different rates. So different types of plastic pipe e.g. PP, PVC, PE etc and different types of metal pipe e.g. HDPE, copper, iron will have
The co-efficient of thermal linear expansion of polyethylene varies with temperature but at aient lies in the range 1.2 to 2.4 x 10-4 per degree C. In broad terms, this is about twenty times that of HDPE, and therefore unrestrained pipe will expand or contract much PE100

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
The thermal expansion coefficient of concrete ranges from about 7 to 12 microstrains/ C, whereas the one of HDPE seems to be about 80 to 200 microstrains/ C, so it has to be Puhui Pipe manufacturer in China
