- Apr 16, 2018 -

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.
