Abstract

[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to first pickle the steel parts to remove the iron oxide on the surface of the steel parts. After pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.
[0003] In the hot-dip galvanizing production process, a clamp is needed to clamp the workpiece, especially the galvanized pipe. In the prior art, two semicircular hoops with opening and closing are generally arranged on the side of the pipe to provide clamping. Since the lengths and diameters of different pipes are different, the clamping part needs to be replaced frequently to ensure the clamping effect. Not only is the operation cumbersome, but the clamping effect cannot be effectively guaranteed. Utility Model Content
