Technical Informations / Linear Expansion

Produced from PP-R Type-3 raw material, Composite pipes stretches 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)
