Dobycha Noyabrsk and utilised in developing the Chayanda gas field in Yakutia, destined to become a source of gas for the Power of Siberia pipeline, currently under construction. TMK has also been awarded a contract for the supply of steel seamless oil pipeline tubes worth more than RUB 300mn. By February 2016, 718 tonnes of these products will be supplied to Gazprom Dobycha Shelf Yuzhno-Sakhalinsk. an in-house integrated facility for the production of raw materials. Round bars of different austenitic, ferritic, Duplex and Super Duplex grades are produced by conducting quality checks at different stages of manufacturing, before finally being used by the seamless tubes division. CSL uses the cross roll piercing method for production of defect-free seamless stainless steel hollows. The use of in-house produced billets with controlled cleanliness levels and OD peeling has helped in eliminating surface inclusions. Maintaining limited delta ferrite levels in the raw material has contributed towards avoidance of cracks. Rolling is carried out at minimum temperatures

The company’s production facility for seamless tubes is supported by machines that comply with high quality standards. The steel plant at Umbergaon, India, has

to improve surface finish and eliminate rupture, and a process has been set of high-pressure water descaling of billet, before rolling. CSL regularly uses glass lubrication on OD and ID of billets during rolling, and has eliminated surface defects through minimisation of surface torsional and circumferential stress deformation by adjusting feed and cross roll angles. Tube straightening machines ensure minimal residual stress level in the products, which is specifically required for critical applications.
