0.5-25mm Galvanized Pipe Hot Dip 20-325 Diameter
Welded steel pipes with hot dip coating or electric-galvanized coating on the surface of galvanized steel pipes. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, not only as pipelines for water, gas, oil and other general low-pressure fluids, but also as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensation coolers, tubes for coal distillation and washing oil exchanges in chemical coking equipment, and tubes for trestle pipe piles and support frames in mine tunnels.
The hot-dip galvanized pipe is to make the molten metal and the iron matrix react to produce an alloy layer, so that the matrix and the 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 the pickling, it is cleaned in a tank of ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to In the hot dip plating tank.
