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.
Material: Top quality HDPE raw materials .
Color available: white for cold water, yellow color for gas.
Related references: ASTM F 1281/1282 standards.
Packing length: packed by rolls, each roll length can be 50 meters to 500 meters.
Both overlapped welded PE-AL-PE multilayers and laser welded PE-AL-PE multilayers are available.
Risong PE-AL-PE multilayer pipes comply with ASTM F 1281/1282 standards, and can meet all techinical requirements as follows:
|For Water||For gas||For water||For gas|
Risong PE-AL-PE multilayer pipes are mainly used at:
● Cold water plumbing system.
● Coal gas and natural gas pipes.
