OMK Produces Small Diameter Electric Welded Tubing for Rosneft

Russian pipe maker United Metallurgical Company OMK, a Metal-Expo regular exhibitor,has produced the first commercial batch of 60.32 mm high strength tubing from its own hot-rolled steel for Rosneft. The batch was accepted by the customer without any comments. OMK was one of the first in Russia to master the production of electric welded tubing of such a small diameter.

The main share of pipes of this diameter is present on the domestic market in a seamless design. OMK is producing tubing on the basis of the new electric-welded pipe shop at its Vyksa plant in Nizhny Novgorod region in Russia. Since the start of production in July 2020, it has already launched production of tubing pipes with diameters of 73.02 mm and 88.9 mm and pipes for oil and gas pipelines.

OMK began production of a new product type for itself - tubing after the commissioning of a new electric pipe welding shop in the Nizhny Novgorod Region in July 2020. To connect tubing, couplings with triangular threads (NU, tubing) of our own production are used. The workshop with a finishing center for threading and product testing is the only one in Russia capable of producing the entire range of oil and gas pipelines, tubing and casing pipes, including those with premium and semi-premium connections. The most advanced technological lines from the leading international and Russian manufacturers are installed here. A modern electric welding machine for flexible forming from Nakata & Mitsubishi Co makes it possible to produce pipes of strength groups J55, K72, N80 without additional heat treatment.

All new OMK products are manufactured in accordance with Russian and international standards: GOST 31446-2017, API Spec 5CT and GOST 52203-2004 with standard couplings with triangular threads (NU, NKTN) of our own production.
