Production process: DIN series tubes, cold drawn and bright annealed precision seamless
steel tube is used as the tube to be phosphated. The
phosphorization is realized with the imported chemical fluid to
form a black film. The antirust oil is absorbed by means of the
micropore on the film to prevent the tubes from getting rust.
Main Features: Bright black color is homogeneously distributed on the tube
surface. The tube has good property of antirust.
Main Application: Phosphated hydraulic tube is mainly used in hydraulic system. Our products are widely used in: Engineering machinery Machine tool industry Hydraulic industry
Special vehicle Automobile pipeline Heavy machinery Compressor Shipbuilding
industry Railway locomotive Diesel engine Utility boiler Injection molding
machine Power equipment Heavy duty automobile Forging and stamping machine
Main Characteristics: No Oxidation Layer on the Outer and Inner Walls No Crack under Flaring and Flattening No Leakage under High Pressure No Distortion after Cold Bending High Precision High Cleanness Excellent Brightness
