Product Details
Hot dipped gi steel pipe welded tube galvanized square pipe for
construction
The hot-dip galvanized pipe is to make the molten metal and the
iron matrix react 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 the pickling, it is cleaned in a tank of
ammonium chloride or zinc chloride aqueous solution or a mixed
aqueous solution of ammonium chloride and zinc chloride, and then
sent to In the hot dip plating tank. |
