The key is management of the resultant thermal strain. As with all materials, expansion and contraction must be taken into consideration when designing a HDPE piping system. Buried pipelines usually do not move due to soil friction. However, thermal effects must be considered for above grade applications.

What is the difference between HDPE and HDPE?What is the difference between HDPE and HDPE?HDPE has a lower modulus of elasticity and higher coefficient of thermal expansion than other pipe materials. These properties cause HDPE pipe to expand and contract much more from changes in temperature and/or pressure than other piping materials.IMPORTANT INFORMATION What is the temperature of a PVC pipe?What is the temperature of a PVC pipe?The higher expansion coefficients for plastic materials makes plastic pipes and tubes extremely sensitive to temperature changes. Always pay attention to plastic pipes and tubes when temperature varies. A PVC pipe with length 6 m is heated from 0 oC to 60 oC.Temperature Expansion Coefficients common Piping MaterialsABOVE-GROUND HIGH DENSITY POLYETHYLENE

FRP will change 1 in length per 100 of pipe per 100ºF change in temperature. HDPE will change 10 in length with the same conditions. This expansion and contraction of HDPE is critical whenHow much does HDPE sheet expand and contract? iPolyIndoor applications experience little to no expansion as the temperature is constant. For outdoor ambient temperature applications, the rule of thumb is that a 4 x 8 sheet will expand as much as 1/2" in length from a hot summer day to sub-zero winter temperatures in cold climates. HDPE sheet expands more in length than in width, due to its molecular structure.
