Q235B Galvanized steel pipe Features
Galvanized pipe, also known as galvanized steel pipe, divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer thick, with uniform coating, strong adhesion, long service life and other advantages. Electric galvanized cost is low, the surface is not very smooth, its own corrosion resistance is much worse than hot dip galvanized pipe.

Processing Technology Of Q235B Galvanized steel pipe
In order to improve the corrosion resistance of steel pipe, the ordinary steel pipe was galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric dip galvanized, hot dip galvanized layer thick, electric dip galvanized cost is low, the surface is not very smooth. Oxygen blowing welding pipe: used for oxygen blowing steel pipe, generally with small diameter welded steel pipe, specifications by 3/8-2 inches eight kinds. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some of the effective aluminizing treatment.
