ISO9001 Galvanized Steel Square Tubing s235jr welded 2 inch q195
Hot-dip galvanized pipe 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 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 the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solutionof ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. |
