How is galvanized pipe produced? How much do you know?
Galvanized pipes, also known as galvanized steel pipes, are divided into hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing galvanized layer is thick, with uniform plating, strong adhesion and long service life. The cost of electroplating is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
