Water supply PE-Xa EVOH tubing 16mm-32mm Underfloor Heating
PEX-a EVOH Pipe
The external coating of oxygen barrier PEX tubing effectively prevents the diffusion of oxygen molecules into the water through the pipe's walls. This feature prevents the system's corrosion of cast iron components (circulator pumps, air purgers, fill valves, boiler heating elements, etc.). It allows using it in hot water hydronic heating applications, including baseboard/radiator heating, fan coils, and radiant floor heating applications.

Characteristics
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.
Product Advantage:
Cross-linked structure make good flexible pipe
Cross-linked structure,high flexible, good heat and creep resistance,long life time more than 50 years.
Heat-resistance and anti-cold,stable used.
Better performance of cold and hot resistance,temperature range:-20ºC-+95ºC, heat conductivity coefficient 0.40W/m.k, and good thermal conductivity without scaling.
Good pressure resistance
In the floor radiant system,the pressure performance of PEX-a pipe is 1/3 higher than PPR pipe with the same thickness; In the Radiator heating system,the pressure performance of PEX-a pipe is 2/3 higher than PPR pipe with the same thickness;
Better softness,easy installation
Planar structure makes the pipe softness and easy to bend, small internal stress and convenient installation.
Application Areas:
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
