Black Phosphated Hydraulic Tubes with High Precision

We are manufacturer of Seamless Steel Tubes in China, if you want to buy Seamless Carbon Steel Tube, Oil Cylinder Steel Tube, Precision Seamless Steel Tube, Hydraulic Cylinder Steel Tube, please contact us.

Black Phosphated Hydraulic Tubes are produced from Material:

Carbon Steel Standard: EN 10305-1  E235 E355 etc

Shape: Round

Application: Hydraulic System

Production Method: Seamless Cold Drawn Heat Treatment: Bright Annealed

Black Phosphated Tubes Characteristic: DIN Series 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:

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.
