    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, prospecting machinery and other manufacturing industries. ASTM A53 Galvanized Steel Pipe is a welded steel pipe with hot-dip or electro galvanized surface.  Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life.  The galvanized pipe is widely used, not only as the pipeline for water delivery, gas, oil and other general low-pressure fluid, but also as the oil well pipe and oil pipe of the petroleum industry, especially the offshore oil field, the oil heater, condensate cooler, coal distillate wash oil exchanger pipe of the chemical coking equipment, as well as the trestle pipe pile, the support frame pipe of the mine tunnel, etc.   ASTM A53 Galvanized Steel Pipe is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and 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 by ammonium chloride or zinc chloride aqueous solution or the mixture of ammonium chloride and zinc chloride aqueous solution tank, and then it is sent into the hot dip galvanizing tank.  Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
