Hot Galvanized LSAW Steel Pipe
Zinc layer:More than 75um
Other erw welded steel pipe,seamless steel pipe also available.
Hot-dip galvanized steel pipes are widely used in construction, machinery, coal, chemical, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery and other manufacturing industries.
Galvanized steel pipes are welded with hot-dip or galvanized steel. Zinc plating can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes 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.
The hot-dip galvanized tube is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. 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, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. Hot-dip galvanized steel pipe base
Galvanized tube (3 sheets)
Complex physical and chemical reactions with the molten bath to form a corrosion-resistant, compact zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe base, so it has strong corrosion resistance.
