140 tons of corrosion-resistant bimetallic rolling was required for urgent repair of equipment of a large oil refinery.
improved technology allowed to reduce the production chain and get bimetal with composition 09G2S-1508X13 (previously the production period was from 45 from 45 days).
the use of bimetal allows you to increase the reliability and life of equipment operating at high temperatures under pressure in conditions of interaction with aggressive environments up to 30 years and more than the years.
Andrey Leshchenko, Head of the Directorate for Work with machine -building companies:
Severstal has technical competencies for the production of bimetal rolling Two of the four known methods is the method of electroslak surfacing with the subsequent rental and the package rolling method. The uniqueness of the company's proposal is the ability to quickly master the production of new compositions. And this uniqueness is ensured by the fact that the entire technological chain is concentrated within the framework of one enterprise. Currently, the main demand for bimetal is formed by manufacturers of equipment for oil and gas processing industries - coke chambers, adsorber, absorbers, column and reactor equipment. But we see the potential in expanding the scope of bimetal and are ready to develop new engineering solutions and compositions. ”
also in 2025, thanks to the work of the directorate for technical development and quality, sheets of bimetallic rolling of a total thickness of less than 16 mm and more than 115 mm were first carried out and more than 115 mm. Bimetal according to the ASME SA-263-20 standard, consisting of steel of the GRADE 12 CLASS2 brand as the main layer and 410S-a crumbling, and bimetal for the production of large diameter pipes.
