hot dip galvanizing hot dipped alloy steel pipe

Hot dip galvanizing TPMCSTEELHot 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 450 176;C. As ISO 1461, ASTM A123, and EN10240, the galvanizing process has its own builtin means of quality control because zinc does not react with an unclean steel surface.
