Product Description
Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery, greenhouse construction and other manufacturing industries.Galvanized steel pipe Welded steel pipe with hot-dip coating or galvanized coating. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, in addition to general low-pressure fluids such as water, gas, oil and other pipelines, they are also used in the petroleum industry, especially in offshore oilfield oil well pipes, oil pipes, oil heaters for chemical coking equipment, and coal distillation oil washing coolers Condensation and exchange of pipes, as well as trestle piles, mine roadway support frame pipes, etc.
The hot-dip galvanized pipe is formed by the reaction of molten metal and iron matrix to form 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 iron oxide on the surface of the steel pipe, after pickling, it should be washed in an ammonium chloride or zinc chloride solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. A complex physical and chemical reaction occurs between the matrix of the hot-dip galvanized steel pipe and the molten pool to form a dense corrosion-resistant zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix, and has strong corrosion resistance.

FAQ
The excellent quality of our steel is demonstrated by its uniformity, ease of forging, good hardening and tempering, resistance or overcoming force, and elasticity. In order to determine the first point, surface grinding and polishing should be carried out on the wheel when its shine and texture appear.
