I have floor heating in my house. I wanted to buy Poly's PE-XC, but I ended up in Poly's floor heating shop. They tricked me into buying PE-XB. Paulie's people said it was guaranteed.

PeX pipe is a pipe made of PE plastic transformed into PEX material with high temperature resistance and aging resistance by physical or chemical means. It was originally used as a cable shell. PEX is divided into PE-Xa, PE-Xb and PE-Xc.

Tube A and tube C are planar reticular structures connected by carbon-carbon bonds. B tube is a three-dimensional network structure, connected by silicon-oxygen bond.

High temperature resistance, B tube is the best, followed by A tube and C tube.

Strength, tube B is the best and tube A is the weakest.

The aging resistance of tube B is also the highest.

Comprehensive safety performance, PE-Xb is the best. The only drawback is that the density of B and C pipes is high, which is more difficult to warm than that of A pipe, and the installation master is more laborious.

Large and small manufacturers in the market can produce A tubes, which are mixed, and C tubes are generally produced by cable manufacturers. Only the B pipe has high requirements for equipment and high cost, and few domestic companies have the strength to do it. Relatively speaking, there will be a lot of PEX-b on the market that works well, but it's really fake.

On the whole, PE-Xb is the best PEX tube, but customers need to buy it carefully and merchants need to choose materials carefully.
