High quality PEX-a pipe with GOST certificate for underfloor heating system
1.Products Description
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.

2.Pipe Advantages
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.
Thermal memory,fast recovery
The particular "memory performance" could make the pipe fast recover when deformed by the outside force,and it also guarantee the sealing of the connected position.
3. Pipe 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

7.FAQ
Q1. What material of pipe are you specialized in?
A: We manufacture PE-Xa, PPR, PE-RT, PEX Aluminum composite pipes and fittings.
Q2. Do you produce PVC pipes and fittings?
A:Sorry, dear friend. We are more professional PE and PPR pipe and fittings, which are more suitable for drinking water as they are more hygienic than PVC material.
Q3. Please tell me your largest outer diameter for pipes.
A: We can produce 8mm-- 110mm diameter (PE pipe).
Q4. The price of your products is higher than others.
A: We can't promise you the best price, but we can promise you the best quality. We import raw material from famous companies such as Borstar, LG Chemical, Chervrom, Hyosung, Lydellbasell, Sinopec.
Q5. For pipe fittings, what do you do mainly?
A: For fittings, coupling (socket), elbows, tee, reducer, union, valve, cap and copper insert fittings are our main products.
Q6: Can you provide us some samples for testing?
A: Of course, my friend. For small amount of samples, we can provide you for free.
