Steel Pipes with high precision for Hydraulic Systems Black Phosphating
Production process for steel precision tubes:
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 of precision seamless steel pipe tube:
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.
