Recently, good news came from Kuwait Oil Company that the super duplex stainless steel pipe products produced by Qingshan Iron and Steel passed the acceptance test. This means that Qingshan Iron and Steel super duplex stainless steel pipe has been successfully applied to the Middle East oil pipeline transportation, and Qingshan Iron and Steel has once again made a major breakthrough in the development of high-end stainless steel products.
In 2016, Qingshan Iron and Steel personnel negotiated to harvest orders for super duplex stainless steel pipes for Middle East oil pipelines. Subsequently, the company quickly organized its production, sales and research teams for research and development and production. It is understood that the super duplex stainless steel seamless pipe products have experienced more than 30 process flows. Qingtuo Research Institute, Qingtuo Nickel Industry and Qingshan Steel Pipe precisely control all the details and processes, and finally let the product technical indicators meet the demanding requirements of KOC.
Super duplex stainless steel combines the advantages of austenitic and ferritic stainless steels with excellent resistance to harsh media corrosion, good strength, toughness and weldability, and is widely used in demanding applications. The climatic conditions in the Middle East are harsh, and the requirements for oil pipelines are high. Pipes are required to meet the conditions of pressure resistance, cold and heat exchange resistance, corrosion resistance, etc. Therefore, customers choose to use super duplex stainless steel.
Super duplex stainless steel production technology is difficult, only a few companies in China can produce, and have not yet formed enough production capacity.
