Steel Pipes with high precision for Hydraulic Systems Black
Black Phosphated Hydraulic Tubes with High Precision
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.
Bright black color is homogeneously distributed on the tube
surface. The tube has good property of antirust.
Phosphated hydraulic tube is mainly used in hydraulic system.
