PVC, CPVC, Carbon Steel, Stainless Steel and Fiberglass Pipes - Thermal Expansion Diagrams
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:
| Thermal Expansion (inches/100 feet) | |||||
|---|---|---|---|---|---|
| Temperature Change (oF) | Fiberglass | PVC1) | CPVC1) | Carbon Steel | Stainless Steel |
| 25 | 0.31 | 0.90 | 1.14 | 0.18 | 0.27 |
| 50 | 0.61 | 1.80 | 2.28 | 0.36 | 0.54 |
| 75 | 0.92 | 2.70 | 3.42 | 0.54 | 0.82 |
| 100 | 1.23 | 3.60 | 4.56 | 0.72 | 1.09 |
| 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.
