PAO Severstal, one of the world's largest vertically integrated
steel and mining companies, was set in December 2019 and January
2020 to address the Zagorsk factory pipe 50 thousand tons of corrosion resistant
strip produced at the mill 5000 for the production of tubular steel products,
located in the Kolpino industrial site.
the production Technology of innovative corrosion resistant strip K52 was
developed by technical professionals manufacture tubular steel products in the
shortest possible time. Analyzed the furnaces and temperature
profile of the rental before and after ultrasonic inspection, examined the effects of
the metal structure on the complex of mechanical and corrosion properties are investigated
influence pipe process stage, using the power of the Izhora pipe plant.
corrosion resistant strip K52 has a unique range of mechanical and
corrosion characteristics. Metal properties provide operational
the reliability of the pipeline operating at a pressure up to 9.8 MPa, with a minimum
operating temperature -20°C.
the Tube made from such sheet metal, will be used when
the transmission of natural gas containing hydrogen sulfide, the partial pressure of
which will reach 1.5 MPa. It is the ability to provide uninterrupted
the operation of the pipeline with the same content of hydrogen sulfide and allows you to call
metal resistant to hydrogen sulfide cracking.
"the Portfolio of orders for the production of tubular steel products more formed from
the new complex products. The experience we gained will help us
significantly speed up the development of new products tailored to the needs of our
customers", - said the Director of manufacturing tubular steel products - General
Director of JSC "Izhora pipe plant" Artem Akinfeev.
"the Joint work of specialists of the Zagorsk pipe plant and the company
"Severstal", aimed at the supply of corrosion resistant strip K52, you can
be described as productive. In the middle of last year we talked about how
they intend to enter the market of tubes, resistant to hydrogen sulfide cracking,
and we did it," - said the commercial Director of the Zagorsk tube
plant Dmitry Simankov.
