Galvanization method for seamless steel pipe There are two major categories of hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has wet method, dry method, lead-zinc method, redox method, etc., and the process flow is shown in the figure. The main difference between different hot-dip galvanizing methods is how to activate the surface of the pipe to improve the galvanizing quality after the acid pipe is cleaned. The dry process and redox process are mainly used in production, and their characteristics are shown in the table. The zinc-plated zinc layer has a very smooth and compact surface and uniform structure; it has good mechanical properties and corrosion resistance; zinc consumption is 60% to 75% lower than that of hot-dip galvanizing. Electro-galvanizing has certain technical complexity, but it must be applied to single-sided coatings, double-sided coatings with different thicknesses on the inner and outer surfaces, and thin-walled tubes.
