Aluminum-plastic ppr pipe

PPR-AL-PPR pipe,high quality with lower price, of 50 years use  

The PPR-AL-PPR pipe is five-layer composite pipe that combines the advantages of a mental and common PPR pipe and avoids the disadvantages of both at the same time. The aluminum core is absolutely diffusion tight; it reliably prevents oxygen/gases from permeating into pipe. It compensates and reduces snap-back forces and heat expansion with changes of temperature.
