The wall thickness can reach 0.25mm, and the outer diameter of the thin-walled tube can reach 5mm. The wall thickness is less than 0.25mm, and the dimensional accuracy of cold rolling is higher than that of hot rolling.


It has good comprehensive mechanical properties, good weldability, cold and hot working properties and corrosion resistance, and has good low temperature toughness.


DN125-DN150-DN200 Galvanized Steel Pipe


The dimensional accuracy requirements are relatively low, and the plate shape problem is not easy to occur, and the main control is the convexity.
