Hot-dip Galvanized Pipe and Cold-galvanized Pipe

The hot-dip galvanized steel tube is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is the first step of pickling the steel pipe in order to remove the iron oxide on the surface of the steel pipe.

Hot dip galvanizing - TPMCSTEEL

Hot dip galvanizing is the process of coating pipe and fitting with a layer of zinc alloy in a bath of molten zinc at temperature around 450 °C. As ISO 1461, ASTM A123, and EN10240, the galvanizing process has its own built-in means of quality control because zinc does not react with an unclean steel surface.
