Hot dip galvanized steel pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating are combined. Hot dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, the steel pipe is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Steel grade: q215a; Q215B; Q235A; Q235B.Test pressure value / MPA: d10.2-168.3mm is 3Mpa; 5 MPa for d177.8-323.9 mm. It is mainly used for conveying gas, heating, domestic water supply and drainage, fire protection, etc
