Composite pipes
The white Danfoss FH composite pipe is 100% oxygen-tight, temperature-resistant, and highly flexible. It features an aluminum core, coated inside and out with polyethylene (PE-RT) layers, permanently bonded via adhesive.
The octene side chains in PE-RT provide properties similar to cross-linked polyethylene (PE-X), delivering excellent long-term hydrostatic strength at high temperatures without crosslinking.
The aluminum layer ensures the pipe retains its shape once bent, making installation easier and maintaining oxygen-tightness for a long-lasting floor heating system.
Manufactured in accordance with ISO 21003.
Features and benefits
- Shape retention - The aluminum layer gives the pipe a “memory” — once bent into position, it stays in place without springing back
- Oxygen tightness – 100% oxygen tight aluminum core
- Dimensional stability – less thermal expansion compared to all-PE-X pipes, making it ideal for installation in floor panels and helping to avoid noise issues
- Best pressure and temperature ratings due to strong aluminum core
- Lifetime up to 50 years
