OMK Chelyabinsk Supplies Bends for Yamal Peninsula Oil & Gas Field
The Chelyabinsk plant of the United Metallurgical Company OMK has supplied 391 branches to Gazpromneft-Yamal for arranging well clusters at the Novoportovskoye oil and gas condensate field located on the Yamal Peninsula. The order was completed from March to June 2021. The products are designed to work in the Far North at temperatures up to minus 60 degrees Celsius. To ensure high corrosion resistance of the bends, they are made of high strength anticorrosive steel pipes. OMK also applied external anti-corrosion insulation using a special epoxy-based material that meets all the customer's requirements. The use of this material as a coating has more than halved the production time. In addition, an external heat insulating coating with a skin effect system was applied to all bends. The system makes it possible to heat oil in a pipe by using a satellite pipe through which an induction current flows.
To fulfill this order, the Chelyabinsk plant OMK used pipes with a diameter of 530 mm and a wall thickness of 10 mm produced by the Vyksa plant OMK in Nizhny Novgorod region.
The skin effect system is used in the oil industry for industrial heating of long pipelines located in the northern territories. This technology makes it possible to partially or completely compensate for heat losses, maintain the optimal temperature of the liquid in the pipe, or heat it up to a predetermined temperature.
