Thermal Expansion of PVC, CPVC, Carbon Steel, Stainless Steel and Fiberglass Pipes

Typical thermal expansion of PVC, CPVC, Carbon and Stainless Steel and Fiberglass pipes

Thermal expansion of pipes in PVC, CPVC, Fiberglass and Carbon or Stainless Steel in inches per 100 feet can be found in the diagrams and table below:

Pipes - thermal expansion diagram - fahrenheit

Pipes - thermal expansion diagram - celsius

150 1.84 5.40 6.84 1.08 1.63

For temperature change: 1 oF = 5/9 oC

1) Note the relative huge thermal expansion of thermoplastic plastic materials - like PVC and CPVC - compared to steel.
