Hot-dip galvanized steel pipe, in order to improve the corrosion resistance of steel pipe, galvanized steel pipe in general. Galvanized steel pipe is divided into two kinds: hot-dip galvanized and electro-galvanized. Hot-dip galvanized has a thick layer and electro-galvanized has a low cost, and the surface is not smooth.
Hot-dip galvanized layers are considered to be highly ductile because they retain their full corrosion protection even after severe forming (drawing). This is because the zinc layer is tightly bonded to the tube and has a low tendency to flake due to its low friction surface.

Galvanized steel pipe is the carbon steel pipe that are coated with a protective layer of zinc. The zinc layer served as a sacrificial layer, it will get rust before the carbon steel under neath it. Galvanized steel tubeS include Two types: hot dipped galvanized steel pipe and cold galvanized steel pipe. Galvanized layer will strengthen the anti-corrosion performances of steel pipe.
