Product Introduction
Galvanized steel pipe is an alloy layer formed by the reaction between molten metal and iron matrix, which combines the matrix and the coating. Hot-dip galvanizing is a process of pickling steel pipes. In order to remove the iron oxide on the surface of steel pipes, after pickling, the pipes are cleaned through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot-dip galvanizing tank.Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube matrix and the molten plating solution, resulting in a zinc-iron alloy layer with a close corrosion resistance structure. The alloy layer is integrated with pure zinc layer and steel tube matrix. Therefore, it has strong corrosion resistance. Galvanized steel pipe are widely used, in addition to pipelines for general low-pressure fluids such as water, gas, oil, etc., and also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensation of chemical coking equipment. Cooler, coal distillate oil exchanger pipe, and trestle pipe pile, support pipe for mine tunnel, etc.
