Technical Informations / Linear Expansion
Produced from PP-R Type-3 raw material, Composite pipes strechs in hot and contracts in cold due to its physical structure. Piping systems longer than 5 m must comply with expansion rules.
Linear expansion is calculated with below formulae:
| Pipe Length | Temperature Difference DT (°C) | |||||||
|---|---|---|---|---|---|---|---|---|
| L(m) | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 |
| 1,0 | 0,30 | 0,60 | 0,90 | 1,20 | 1,50 | 1,80 | 2,10 | 2,40 |
| 2,0 | 0,60 | 1,20 | 1,80 | 2,40 | 3,00 | 3,60 | 4,20 | 4,80 |
