Description:

Synopsis of Process Routing: Cold drawn and bright NBK 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 micro pore 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, shippment industry,nested card connector (pipe joints) with matching.

Applications:

Used in hydraulic system,nested card connector (pipe joints) with matching,,automobile and in the occasion where the high precision,brightness,cleanness and mechanical properties of the tube are required

Specifications:

Outside diameter ranges from 4 to 60 mm and wall thickness ranges from 0.5 to 7mm. Precision steel tubes are delivered according to EN10305-4.
