High Quality Standard Hollow Tube Galvanized Steel Tubing Hot Dip Galvanized Round Pipe

Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.

Galvanized steel pipes are welded steel pipes with hot-dip or electro-galvanized layers on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used, in addition to being used as line pipes for water, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensate coolers, coal distillation and oil exchangers for chemical coking equipment, as well as trestle pipe piles, and pipes for support frames of mine tunnels.

Hot-dip galvanized pipe is to react molten metal with iron matrix 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 pickling, it is cleaned in an aqueous solution of ammonium chloride or zinc chloride or an aqueous solution mixed with ammonium chloride and zinc chloride, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe matrix undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant and compact zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix, so it has strong corrosion resistance.
