Steel Pipes with high precision for Hydraulic Systems with Black Phosphating surface
Black Phosphated Hydraulic Tubes with High Precision and tight tolerance, the tubes are produced by precision cold drawn and cold rolling, then bright annealed in a protected atmosphere, afterwards it is blackphosphated on the surface
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.
Seamless Precision Steel Pipe Size range:
O.D.:5-80mm W.T.:1-15mm L:max12000mm
Main Application:
Phosphated hydraulic tube is mainly used in hydraulic system.
