Product Q&A

Q:Is your pipe a 3-layer or 5-layer structure?

We offer 3-layer PEX EVOH pipe. The 3-layer structure (PEX-EVOH-PEX) has the oxygen barrier layer in the middle, which effectively prevents physical damage during installation and provides longer-lasting oxygen barrier performance.

Q:What sizes do you support?

Common sizes include 12mm, 16mm, 20mm, 25mm, and 32mm. The wall thickness is typically 2.0mm, and can also be customized according to your local standards.

Q:What are the packaging specifications? How many meters per roll?

Standard packaging is 100m, 200m, or 300m per roll. We can supply OEM carton packaging and print codes on the pipe surface.

Q:What is the main function of the EVOH layer? (Why is an EVOH layer needed?)

The EVOH layer prevents oxygen from permeating into the piping system, effectively protecting metal components in heating systems (such as boilers and manifolds) from oxidation and corrosion, thereby extending the service life of the entire system.

Q:What is the difference between PEX-a, PEX-b, and PEX-c?

PEX-a (Peroxide method): Best flexibility, has "memory function", and strong freeze-crack resistance. PEX-b (Silane crosslinking method): Higher stiffness, cost-effective, and currently the mainstream product shipped from our international platform. PEX-c (Radiation crosslinking method): Good environmental performance, but relatively higher price.
