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.
