Large-diameter coated steel pipe

"Six" brand water with the coated composite steel, it has both the strength of steel pipe, another plastic pipe corrosion and wear, fluid resistance, etc, is a new water supply, pipeline corrosion. It is easy to overcome the galvanized pipes rust, resulting in yellow water, product pipeline diameter masonry produce small, plug, plastic tube defects such as strength of the weak, to prevent secondary pollution, improve water quality have marked effects. Reference implementation of the standards: CJ/T120-2008 "coated composite water supply pipe" GB/T17219-1998 "the implementation of health performance standards Internal and external coating Material: polyethylene (PE), heat resistant polyethylene (PE-RT), cross-linked polyethylene (PEX), epoxy resin (EP), polyurethane (PU) "Six" brand coated composite pipe based management with ordinary hot dip galvanized welded steel pipe (or pipe, spiral pipe, seamless pipe) of the surface, heated jet (roll, smoke, dip) coating plastic powder and
