•Production process control:We use the domestic first-class drawing machine,the production process is
controlled with alloy internal and external matrix to control product dimensions, through the first, middle
and last process inspection to ensure product quality.
•Finished tube anti-rust oil plating equipment:We adopt high pressure spray plating method, the antirust
oil is plated by high pressure jet after ten passes of filtering and one pass of precipitation to safeguard
the tubes’ outer and inner surface cleaness and polishness.
•Inner and Outer Surface Cleaning Equipment: We adopt automatic inner surface cleaning machine,
rotating brush cleaning and high pressure oil flushing to clean the inner and outer surface.The new
steel tube production craftsmanship can effectively remove all particulate attached to the inner and outer
surface of tubes and thus achieving the utmost surface cleaness and polishness.
