Description

Technical Field

[0001] The utility model belongs to the technical field of hot-dip galvanized parts, and in particular relates to a hot-dip galvanized part with wear resistance and low thermal conductivity. Background Art

[0002] Hot-dip galvanizing refers to the galvanizing of general steel pipes to improve the corrosion resistance of steel pipes. Hot-dip galvanized pipes are made by reacting molten metal with the iron matrix to produce an alloy layer, thereby combining the matrix and the coating. 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 ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of 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 steel pipe matrix undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, it has strong corrosion resistance and low thermal conductivity, which reduces the pressure inside the pipe.

[0003] When the existing hot-dip galvanized pipe is in use, a flange is generally welded at the end of the pipe body interface so that the flange can be screwed and fixed with bolts. However, when the hot-dip galvanized pipe is connected through the flange, it is difficult to accurately align the screw holes because there is no docking guide structure. The only way to align the screw holes on the flange is to rotate the pipe body of the hot-dip galvanized pipe. The screw hole alignment operation of this connection method is more troublesome and not convenient enough. Utility Model Content
