Cold-drawn Welded Precision Tube
Introduction:
Using Precision ERW tube as the main raw material, it goes through the anaerobic annealing furnace for oxidation prevention, efficient surface coating treatment, and the drawing process via high-precision equipment. This product features high efficiency, high strength, highprecision, high finish and high straightness. On thataccount, it is widely used in auto mobiles, motorcycles, engineering machinery, machinery manufacturing, etc.
