PPR-GF-PPR
Pipes

Glass-Fiber Reinforced PPR Pipes for
Pressure, Temperature & Dimensional Stability

Edoburg supplies PPR-GF-PPR composite pipe systems manufactured in compliance with DIN 8077 / 8078, engineered for high-pressure, high-temperature applications in infrastructure, mechanical, and utility-grade installations. These multilayer pipes consist of a polypropylene (PPR) inner and outer layer with a central glass-fiber reinforced (GF) core, delivering enhanced rigidity, reduced expansion, and greater dimensional stability under load.

​

Ideal for contractors and EPC firms involved in HVAC, district cooling, industrial fluid transport, and multi-storey plumbing systems, these pipes are available in metric sizes with DIN-standard compatibility and export-ready documentation.

Why Choose PPR-GF-PPR Pipes

  • Up to 75% lower thermal expansion vs regular PPR — ideal for vertical risers and long pipe runs

  • Enhanced structural rigidity — minimises sagging and support requirements

  • Excellent chemical and scale resistance — suitable for aggressive or mineral-laden water

  • Lightweight and weldable — faster installation compared to metal systems

  • Thermally insulated — natural insulating properties reduce energy loss in hot/cold water distribution

Applications

  • Pressurised hot and cold water supply in commercial buildings

  • Central HVAC and district cooling networks

  • Chilled and hot water loops in industrial utilities

  • Compressed air distribution systems

  • Plumbing risers in high-rise residential and hospital projects

  • Pipe networks in mining, food processing, and manufacturing units
