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.

Usages

  • Sanitary hot & cold water piping systems (and potable water application).
  • Risers installation systems.
  • Industrial installations.

Advantages

  • Increased pressure & temperature resistance of the product compared to single-layer PPR pipes.
  • Very low linear expansion coefficient in comparison with single-layer PPR pipes (about 75% less):
  • – Minimizes the changes in the pipe length caused by temperature fluctuations inside the piping system. -Minimizes the number of pipe clips used in the piping system and hence, reduces the costs.
  • Higher mechanical properties as compared to single-layer PPR pipes.
  • Quick and easy installation that saves about 30% of installation time compared with PPR foil pipes.
  • Less heat loss compared to PPR foil pipes and metal ones due to its lower thermal conductivity coefficient.
  • impossibility of layers separation.
  • Lower weight than PPR foil and metal pipes and easy transportation.

Usages

  • Sanitary hot & cold water piping systems (and potable water application).
  • Cooling tower risers.
  • Compressed air distribution systems.
  • Fan coil unit drain piping.
  • Risers installation systems.
