Din internally and externally galvanized steel
Synopsis of process routing: din highly accurate, cold drawn and bright seamless steel tube is used as the tube to be internally and externally galvanized. The inner and outer wall of tube areelectroplate, and/or passivated with military green after galvanizing. The caps are used to cover two ends of tube to prevent from the dust. .
Main features: the inner and outer walls of tube are galvanized and/or passivated which have remarkable properties of antirust and anticorrosion. The zinc white, color zinc (zinc yellow) and passivation with military green can be realized.Note: the length of tube is not exceeded 3m.
Main features of passivation: high anti corrosive performance, salt spray testing as per gb/t10125, testing times for 240 houses, with not rusting.
Main application: used in military industry, automotive and locomotive industries and in the case where the high antirust and anticorrosion for inner and outer tube walls are required
Din galvanized steel tube with high precision
Din cold drawing Synopsis of process routing: quality carbon steel · cold drawing · bright heat treatment without oxidization (nbk status) · nondestructive testing. In the wall honing and inside flushing under the high pressure·. Antirust oiling outside surface·plastic capping on both ends Main features: high accuracy, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness inside wall. The steel tube is able to stand high pressure. No deformation after cold bending, no crack after flaring and flattening . The complicated geometrical forming and machining can be realized. Color of tube: gray with white. Main application: to be used in hydraulic system, automobile and in the occasion where the high precision, brightness, cleanness and mechanical properties of the tube are required.
Din black and phosphated hydraulic tube Synopsis of process routing: din highly accurate, cold drawn and bright seamless steel tube is used as the tube to be phosphated. The phosphated 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 from the rust. The caps are covered at two ends of tube to prevent from the dust. Main features: color of steel tube: bright black. Color is homogeneously distributed on the tube surface. The tube has good property of antirust. Main application: used in hydraulic system. This tube is our main product for export business.
