PE-AL-PE tube exactly work for cold water temperature under 65 degree, PEX-AL-PEX exactly work for hot water temperature up to 95 degree. so we can also say PE means the material for cold water, PEX means the material for hot water.
PE is laminated with the aluminum layer and special glue in the middle. it is also called five layer composite pipe: PE/glue/AL/gluePE.
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 F1282, Spain AENOR, Australia SAI. We also give warranty 2years to customers of quality inspect after goods arrive.
