Synopsis of Process Routing: Cold drawn and bright NBK seamless steel tube is used as the tube to be phosphated. The phosphated is realized with the imported chemical fluid to form a black film. The antirust oil is absorbed by means of the micro pore on the film to prevent from the rust. The caps are covered at two ends of tube to prevent from the dust.
Inner and Outer Surface Cleaning: 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.
Main Application: used in hydraulic system, shippment industry,nested card connector (pipe joints) with matching.
