Hot dip galvanized pipe Description

Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and the coating of the two combination. Hot dip galvanizing is to first pickling the steel pipe. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating 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 substrate and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.

Hot dip galvanized pipe advantage

Hot dip galvanizing: also called hot dip zinc and hot dip galvanizing: it is an effective way of metal anticorrosion. It is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that a layer of zinc layer is attached to the metal components, so as to play the purpose of anticorrosion. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better, so as to play the purpose of anticorrosion.

Hot dip galvanized pipe manufacturing step

Black inspection → hanging → skimming → rinsing → pickling → cleaning → dip plating aid → hot air drying → hot dip galvanizing → Cooling → passivation and rinsing → Unloading → inspection and dressing → packing, warehousing and transportation.

Hot dip galvanized pipe application

Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, mining machinery, greenhouse construction and other manufacturing industries.
