Cold Drawn Seamless Steel Pipe

Our cold drawn seamless steel pipe is manufactured by cold-drawing or cold-bending steel plate or steel belt at normal temperature. Our cold drawn seamless steel tube is a high-tech energy-saving product features fine surface finish, roundness and straightness and uniform wall thickness. The sectioning surface of our product can be molded into various sorts of shapes efficiently without damaging the coating. We can offer cold drawn seamless steel pipe with diameter ranging from 17.1mm to 101.6mm.

Our company conducts cold drawn seamless steel pipe production strictly in accordance with the standard of ISO9001: 2000 quality management system. Rigorous inspection operating specifications on raw material inspection, production process inspection and finished product inspection are formulated to control the pipe quality. In addition, we inspect the inherent quality of the seamless pipes employing scientific methods with the help of scientific instruments and improve our pipe’s overall quality through carrying out scientific experiments.

We are capable of providing customers with 100000t cold drawn seamless steel pipes in diameter of φ18-φ101.6mm and wall thickness of 2mm-14mm per year. 50% of our cold drawn steel tubes are exported to Southeast Asia, Europe and Asian. These steel tubes are widely used as structural tubes, fluid delivery tubes and boiler tubes.
