Product Description
API5L,ASTM 12cr1mov Q235 20# 45# 2.5 inch color painting pre galvanized square steel pipe
Products Description
The molten metal reacts with the iron matrix and produces an alloy layer, so as to combine the matrix and the coating. Hot dip galvanizing is the first steel pipe pickling, in order to remove iron oxide on the surface of the steel pipe, pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
