What standards do your multilayer pipes meet?

Our pipes are made into GB/T18997 standard and can confirm to ASTM F 1281/1282 & EN ISO 21003 standards.

What is the difference between butt welding and overlap welding?

Butt welding uses seamless laser technology for better stability, while overlap welding is an ultrasonic type. Laser welded pipes are less likely to crack when rounded or beveled.

What types of multilayer pipes can you manufacture?

We provide PE-AL-PEXa, PEXb-AL-PEXb, PEXc-AL-PEXc, and PERT-AL-PERT pipes with various diameters and wall thicknesses.
