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.
