Our technical team can assist on the specification of your gas spring or damper product to ensure that the optimal
product is selected or developed for your application.
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
