Global leader in seamless pipe solutions Vallourec strives to shape the future of the energy industry by continuing to develop the production of more advanced products. Already, Vallourec’s site in Jeceaba in Brazil has increased its global exports thanks in part to this strategic approach and now Vallourec Tianda in China is building a portfolio of premium products for local and foreign clients.Vallourec acquired Tianda, consisting of a plant in Chuzhou and another in Changzhou in China in 2016. The following year, the sites began producing commodities for the Asian and Middle Eastern markets. Vallourec Tianda maintains API 5L standards, and performs comprehensive qualification audits of its steel suppliers in order to ensure the highest-quality end products. Since 2020, Vallourec Tianda has drawn on its expertise in commodity manufacturing and on the Group’s global capabilities to begin a shift toward creating premium products.Based on evolving customer needs, Tianda is industrializing new chemical compositions and steel grades to create pipes with superior mechanical properties. The Tianda team first produced the X52QS premium grade in 2020, for outer diameters of 6-12 inches in 6-16 millimeter wall thickness. The following years, X60QS and X65QS premium grades were also industrialized and qualified. Moreover, the Line Pipe manufacturing range has now been extended to ODs up to 14 inches and wall thickness up to 16 mm.Through new alloying concepts involving less carbon, the line pipes offer an effective combination of strength and toughness, as well as high corrosion resistance in a sour service environment. For offshore applications, where improper material properties can cause pipeline collapse, these Vallourec Tianda premium products are proving to be a valuable and reliable solution. Always pushing the envelope, the team intends to develop its offers even further, to provide a full-size range to clients. In 2022, for instance, it announced that its 14 inches OD pipes will have a wall thickness of up to 28 mm. Greater wall thickness means the pipeline can withstand greater pressure, and it offers clients the possibility to develop more complex oil and gas fields.
