Sell Well Pre Galvanized Steel Pipe

Hot dip galvanized round pipe is on the basis of welding steel pipe for internal and external hot dip galvanized, so that the inner and outer walls of steel pipe are coated with zinc layer at the same time, greatly improve the corrosion resistance of steel pipe, up to about 20 times of ordinary steel pipe.

Small diameter galvanized pipe uses butt welding processing method, large diameter steel pipe uses galvanized spiral pipe, according to the size of the cross-sectional area is not the same, choose the appropriate processing technology. When the circumference length of the transverse section of the pipeline is the same, the circle area will be larger than other shapes, and the use of circular pipeline can transport greater flow medium. In addition, when the circular pipeline is subjected to internal and external pressure, the force is more uniform, so most of the pipeline selection is round pipe.
