Overview of the use of galvanized steel pipe

In order to improve the corrosion resistance of steel pipe, the general steel tube (clarinet) was galvanized. Galvanized steel pipe is divided into hot galvanized and electric steel zinc, hot-dip galvanized coating thick, zinc plating cost is low. Oxygen-blowing welded pipe: Used for steelmaking and oxygen-blowing tubes, generally with small-caliber welded steel pipe, specifications from 3/8-inch-2-inch eight kinds. Made of 08, 10, 15, 20 or q195-q235 steel strips. for corrosion protection, and some for aluminizing treatment. Wire Casing: is also ordinary carbon steel welded steel pipe, used in concrete and various structural distribution engineering, commonly used nominal diameter from 13-76mm. The casing wall of the wire sleeve is thinner, most of which is used after coating or galvanized, and the cold bending test is required.
