PE-AL-PE Multilayer Pipes In China

PE-AL-PE Multilayer Pipes

Description:

Just like PEX-AL-PEX multilayer pipes, Risong PE-AL-PE multilayer pipes is also a kind of five-layers' pipe whose inner and layer are made by HDPE material. The aluminum core in middle layer is absolutely diffusion tight, which can reliably prevents oxygen/gases from permeating into the pipe.

● Overlapped welded pipe is co-extrued with one step with perfect adhesive between inner/outer layer of PEX-b and middle layer of aluminum, high and stable pressure resistance, of which welding style is ultrasonic.


● Butt welded pipe is moulded with several steps that is argon-arc welding style.
