In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.

Maintenance is indispensable in the use of galvanized wire. Large coils of galvanized silk should be coated with oil, fiber core immersion oil, oil is required to protect the fiber core is not rotten, not rust, wire moisture fiber, and from the internal lubrication wire rope. Surface coating so that all wire rope strands in the surface, are evenly coated with a layer of rust-proof lubrication grease, which for friction lifting and mineral water large mine rope, to be coated with grinding and water-resistant black oil grease. Coated with red oil with strong film and good rust resistance, it is required to have a thin oil layer, which is easy to keep clean during operation.
