General welded pipe is used for transporting low pressure liquid. Use Q195A, Q215A, Q235A steel manufacturing. Also can be used to other mild steel welding manufacturing. Welded steel pipe for pressure, bending, flattening and so on experiment, the surface quality is a certain request, usually the delivery length is from 4 to 10 m, which often required scale delivery of the goods.
Galvanized steel pipe, in order to improve the corrosion resistance of steel tube, for galvanized welded steel pipe commonly. Zinc galvanization steel tube hot dip galvanized and electrical steel, hot dip galvanized zinc coating thickness, the cost of electric is low. Oxygen tube welding is used for steelmaking oxygen tube. It is generally with small diameter welding pipe, specifications by 3/8 inch - 2 inch eight. With 8, 10, 15, 20, or Q195 - made of Q235 steel strip. For corrosion protection, some aluminized processing.
