Product Description
Q235 Hot-Dipped Galvanized Steel Pipe is a kind of Steel Tube coated with zinc. This coating can protect the galvanized pipes from corrosion and rust, so as to prolong the service life and improve the reliability of the hot-dipped galvanized pipe. Hot dip galvanized tube is to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating. Hot dip galvanizing is to pickle the Steel Pipe first. In order to remove iron oxide on the surface of the steel pipe, after pickling, it is cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
