Referring to GB/T12771-2019 and other relevant national and industrial standards, Dachang stainless steel 2B plate is the raw material, 304/316L material from DN15-DN300 specifications, using advanced mechanical equipment, internal and external inert gas protection, single-sided welding and double-sided forming argon arc welding process, to ensure that the weld is full, silvery, and can withstand greater fluid pressure

The plastic-lined steel composite pipe for water supply is a galvanized steel pipe-based pipe, which has both the mechanical strength of steel pipe and the anti-corrosion properties of plastic pipe by plastic-lined pipe. It uses a self-produced galvanized steel pipe and plastic-lined pipe. The raw materials of the lined pipe are pure imported PE plastic particles and hot melt adhesive and are produced by international or domestic advanced extrusion production lines. The plastic-lined composite pipes include lined PE and lined PE-RT series, in which the lined PE composite pipe is suitable for cold water transportation. The lined PE-RT composite pipe is suitable for hot water transportation.
