Overview of the uses of galvanized steel pipes
2014-07-15
In order to improve the corrosion resistance of steel pipes, general steel pipes (black pipes) are galvanized. Galvanized steel pipes are divided into hot-dip galvanized and electro-galvanized types; hot-dip galvanized has a thicker zinc layer, while electro-galvanized is lower in cost. Oxygen-blowing welding pipe: used as a pipe for oxygen blowing in steelmaking, generally made from small diameter welded steel pipes, with specifications ranging from 3/8 inch to 2 inches in eight varieties. Made from 08, 10, 15, 20 or Q195-Q235 steel strips. To prevent corrosion, some undergo aluminum diffusion treatment. Electrical conduit: also ordinary carbon steel electric welded pipe, used in concrete and various structural distribution projects, commonly with nominal diameters ranging from 13-76mm. The walls of electrical conduits are relatively thin and mostly coated or galvanized before use, requiring cold bending tests.
