As you can see, plastic pipe types usually expand significantly more than metal pipe types. For example, a 50m PE pipe with a +50° temperature differential will expand by 500mm. Designing pipe systems for thermal expansionHow 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.
