NUST MISIS scientists develop Corrosion Resistant SteelSeverko for Oil Pipelines

Release time：Nov 28, 2019 From：admin

The new Russian steel called Severkor for oil pipelines has been created by materials scientists at NUST MISIS in order to reduce the environmental risks of oil production and increase its efficiency due to increased corrosion resistance. A year ago, the first test pipe from the developed steel was installed at the Kokuysky oil and gas field in the Perm Krai territory in Russia. In the fall of 2019, Lukoil company has presented an expert opinion confirming Severkor's unique resistance to the aggressive environment of crude oil and salt solutions. The corrosion rate in the pipe made of new steel was only 0.008 mm per year, that is, the depth of the deterioration from the corrosive liquid effect on the metal was less than the defects in the rolling mill.

Scientists from NUST MISIS have proposed an innovative technology for the rolled steel for the corrosion-resistant field pipes production with improved mechanical characteristics. The new Severkor steel grade will significantly reduce environmental risks and operating costs in oil production, especially in the regions where pipe repair and replacement are complicated by the delivery conditions, and the composition of hydrocarbon materials causes an increased level of corrosion wear.

Severkor has been developed by the NUST MISIS scientists by the order of one of the world's largest metallurgical companies PAO Severstal. The need to develop a new grade of steel was due to the peculiarities of oil development technology in most world deposits.
