Pre Galvanized Steel Pipe

Pre galvanized steel pipe

1. Pre galvanized steel pipe technology:

First on the work of strip steel pickling. In order to remove iron oxide on the surface of the steel strip, after pickling, cleaning by ammonium chloride (zinc chloride) aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution. And then send to hot dip galvanized tank. Air drying and then make pipes. Pre galvanized steel tube has the advantage of coating uniform, shining, cost low. But its corrosion resistance is slightly worse than the hot galvanized pipe because of low galvanizing.
