Алюминий-пластиковые трубы PPR

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. Colors: white, green, grey Application: 1. Hot water, potable water system; 2. Central air conditioning; 3.
