10# Galvanized steel pipe, also known as galvanized pipe, is divided into two kinds of hot-dip galvanized pipe and Electro galvanized pipe. The hot-dip galvanized layer is thick, the coating is uniform, the adhesion is strong, and the service life is long.

Q345 Galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and thecoating of the two combination. Hot dip galvanizing is to first pickling the steel pipe. In order to remove the iron oxide on the surface of the steel pipe , after pickling , it is cleaned by ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank.
