Terrain FUZE HDPE Thermal Expansion Technical Bulletin

Terrain FUZE HDPE offers substantial durability against the flow of hot water. A waste pipe with no mechanical load will tolerate temperatures of up to 80°C and up to 95°C is permissible for a maximum of two minutes. Thermal movement MUST always be accounted for in both locked and expansion systems (explained in the next set of pages). What is high density polyethylene pipe?What is high density polyethylene pipe?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 that of DI and steel and 3 times that of PVC.IMPORTANT INFORMATION 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 thermal expansion of PVC pipe?What is the thermal expansion of PVC pipe?Example - Thermal Expansion of a PVC Pipe. A PVC pipe with length 6 m is heated from 0 oC to 60 oC. Expansion of the pipe can be calculated as. dl = (50.4 10 -6 m/m oC) (6 m) ((60 oC) - (0 oC)) = 0.018 m.Temperature Expansion Coefficients common Piping Materials

estoniaHow To Deal With Thermal Pipe Expansion and Contraction hdpe pipe thermal expansion in estoniaWhat is thermal pipe expansion? It is natural for materials to expand in the heat and contract in the cold, and pipes are not immune to natures laws. Thermal expansion and contraction of pipework is one of the largest dynamic forces acting upon piped services.

Coefficient of thermal expansion is over 10 times that of DI and steel and 3 times that of PVC. In practical terms, this means HDPE pipe shrinks 10 times as much as DI and 3 times as much as PVC when it gets cold. This can loosen any fittings installed on it. Also, its length shrinks 1 inch per 100 feet of pipe length with a 10° F

In such a case, the opposing force from thermal expansion can place impermissibly high stresses in the carrier pipe. Therefore, free expansion must be allowed to occur, but expansion must ultimately be compensated for through system design.
