seamless weld PERT-AL-PERT multilayer pipe
the best plastic pipe for home hot water supply, floor heating system, PERT laminated with the aluminum layer and special glue in the middle.
Within over 15 years working in PEX-AL-PEX pipe 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.
