Cold Drawn Hydraulic Steel Tubing , Precision Seamless Steel Pipe DIN2391
Speficification:
Features:
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.
Internal Surface quality Control: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.
