Product Description

International standard PEX-a pipe/PERT pipe/PPR with Oxygen barrier for underfloor heating 

The cross-linking technology in a generic way means a process through which Polyethylene molecules get links between the polyethylene chains that provide high resistance to pressure and temperature. This makes polyethylene reticulated a material especially suitable for making pipes that can handle water circulation at high pressures and high temperatures up to 95°C.

EVOH Layer
The inner layer is PEX-a pipe,middle layer is adhesive,outer layer is EVOH, the three layer structure make the pipe performance more stable and the thickness is symmetrical.

Anti-bacteria and scale prevention
The Anti-oxygen layer can effectively prevent oxygen from entering the piping system, it inhibits bacterial and algal reproduction,prevent fouling,guarantee the water quality freshly and cleanly.

Anti-corrosion and rust protection
The oxygen transmission rate<0.1g(d:m)3,it can prevent the oxygen from seeping into the piping system,and prevent the water pollution problems caused by corrosion and rust of metal parts in HAVC system.Therefore,it extend the service life of the metal parts such as manifold and boiler in the heating system.
 

Application
Floor radiant heating system
Radiator heating system
Cold and hot water transportation pipes for central air conditioning,common air conditioning and solar water heater.
Cold and hot water transportation pipes for construction
The pipe for refrigerating system and water treatment system
