Overlap-weld PEX-AL-PEX multilayer pipe use for floor heating system
PEX cross-link can be over 60% with cross-link procedure .standard working pressure 1.0Mpa/10bar. PE-Xb is laminated with the aluminum layer and special glue in the middle. it is also called five layer composite pipe: PEX/glue/AL/glue/PEX.
Within over 10 years working in PEX-AL-PEX fields , and after years develop on quality management, now we can do control of quality according to three international standards as: America ASTM F1281, Spain AENOR, Australia SAI. We also give warranty 2years to customers of quality inspect after goods arrive.

Coefficient of heat expansion
≥5D(D means outside diameter)
Coefficient of heat roughness
Following is the condition we must go by when we use it:
Multilayer pipe is five-layer pipe combines the advantages of metal and plastic pipe, while eliminating the disadvantages of both material.
-classified according to application: Cold water pipe, hot water /heating pipe, gas pipe.
-classified according to welding method: Overlap-welded and butt-welded.
