Shanghai Tian Yang Steel Tube Co.,Ltd. is a modern enterprise for tube making which is specialized to make the seamless steel tube of DIN series featured with high accuracy and brightness.
Our high quality seamless steel tubes are made based on the DIN EN (DIN2391 EN10305) Standards. The hot rolled seamless tube produced by Shanghai Bao-steel Company is used as transfer bar of our company. The finished product is made with the exclusive process of cold drawing and/or cold rolling of our company. The steel tube is featured with high precision and high brightness. Because of using the exclusively non-oxidization process of bright heat treatment, the inner and outer walls have high cleanness without oxidized surface. The tube has the excellent mechanical properties, resulting in no leakage under the high pressure, no deformation after cooling bent and no seam after flaring and pressing in different applications.
Currently, we own 4 modern production lines and a complete set of inspection and testing equipments. The annual capacity is up to 15000 tons. We have three series of EN/DIN high precision and high brightness seamless steel tube, stainless steel tube and DOUBLE WALL STEEL TUBE. Our products are extensively used in a variety of industries, such as hydraulic systems, automobile fabrication, military industry, engineering, locomotive, aircraft, shipbuilding, plastic injection molding, pressure mold, machine tool, diesel, petrochemical industry, power station, boiler, etc.
In 2002, our product was introduced to the international market and exported successfully to Germany where the DIN standard was established. In 2004, we were granted the right of self-support our import & export business (which accounts for 50% of our total business). We improved our management system to obtain ISO9001 certification.
Our products have gained a good reputation in international market. Our steel tubes are exported to South Korea, Japan, Greece, South Africa, Turkey, Singapore, Spain, USA, Canada and Taiwan...

DIN Cold Drawing and BA Seamless Tube
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, anti-rust oiling outside surface, plastic capping on both ends.
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.
Used in hydraulic systems, automobiles and where high precision, brightness, cleanness and mechanical tube properties are required.
