PP-R pre-insulated pipe

Large diameter pre-insulated pipe

To meet the growing demand for larger polymer pre-insulated pipework for heat networks, PP-R pipe is available in 160-315mm with larger sizing available on request. 

• Up to 37% lighter than steel and easier to handle
• No expansion bends - saving both installation and material costs
• Up to 19% lower pressure losses than steel
• Excellent corrosion resistance so no leak detection required
• Can be combined easily with REHAU's PE-Xa for a fully polymer heat network
• Over 50 year lifespan at 70^oC and 9.5 bar 

This whitepaper aims to provide district heating specifiers and contractors with key considerations and technical points for the next generation of low carbon heat networks.
