Advantages

  • Anti-sediment, anti-decay and anti-rust.
  • Insignificant pressure drop due to the low roughness coefficient (inside the pipe).
  • Fast and easy to install.
  • Resistant to chemicals (acids,…).
  • Resistant to physical shock and environmental degradation.
  • Guide lines on all pipes and fittings.
  • No microorganisms growth.

Applications

  • Sanitary hot and cold water piping systems.
  • Mechanical riser systems in building installations.
  • Industrial Installations.
  • Drain piping systems for fan coil units.

Advantages

  • Increased pressure and temperature resistance compared to single-layer PP-R pipes.
  • Very low linear expansion coefficient (approximately 75% less than single-layer PP-R pipes), which:
    − Minimizes pipe length changes due to temperature fluctuations
    − Reduces the number of required pipe clips and overall installation costs
  • Higher mechanical strength compared to single-layer PP-R pipes.
  • Fast and easy installation, saving up to 30% of installation time compared to PP-R foil pipes.
  • Reduced heat loss due to lower thermal conductivity compared to PP-R foil and metal pipes.
  • No risk of layer separation.
  • Lighter than PP-R foil and metal pipes, allowing easier handling and transportation.

Applications

  • Heating and cooling installation piping systems.
  • Fan coil unit (FCU) drain piping systems.
  • Cooling tower risers.
  • Sanitary hot and cold water supply systems.
  • Branch connections from boiler room manifolds.
  • Compressed air distribution systems.
