Seamless weld PEX-AL-PEX multilayer pipe use for hot water floor heating system
PEX cross-link can be over 60% with cross-link procedure, 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/gluePEX.
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.
