Hot Dip Galvanized Steel Pipe VS Cold Dip Galvanized Steel Pipe
Hot-dip galvanized steel pipes undergo a meticulous process starting with pickling on the steel components. This initial step aims to eliminate surface iron oxide. Following pickling, a thorough cleaning occurs using an aqueous solution of ammonium chloride, zinc chloride, or a blend of both. The treated steel components are then immersed in a hot-dip electroplating tank. This method offers advantages such as a uniform coating, robust adhesion, and an extended service life. Though less commonly utilized on a large scale today, cold-dip galvanized steel pipes are introduced for the sake of differentiation. Also known as electro-galvanizing, this process involves the removal of oil and pickling using electrolysis equipment. The steel components are then immersed in a zinc salt solution, with a zinc plate connected to the positive electrode of the electrolysis unit. By applying an electric current, zinc is deposited onto the pipe fittings. Cold-dip galvanized fittings undergo initial processing before galvanization. This article will briefly introduce differences between hot-dip and cold-dip galvanized steel pipes.
