Forgings for energy

Forgings for electric power industry (generator shafts, rotor shafts, pinion shafts, shells, gear wheels, couplings, discs, and sleeve tubes).

Production and delivery of forgings for power-plant industry is a priority business segment for LLC Bonus. The main products in this segment include turbine generator rotor shafts, steam turbine rotor shafts, hydraulic shafts and forgings for hydropower industry, forgings for gas transporting plants and gas turbines, forgings for shafts and components of power plant equipment, etc.

Generator rotor shafts are made of steel grades 38CrNi3MoVA, 35CrNi3MoVA, 34CrNi1MoA, 26NiCrMoV115 and others. Forging is performed on ingots weighing up to 15 tons.

Turbine rotor shafts for high-pressure, medium-pressure and low-pressure cylinders are made of steel grades 25Cr1Mo1VA, 30CrNi3Mo1VA, 26CrNi3Mo2VA, 23CrMoNiWV88 and others. Forging ingot weighs up to 15 tons; finished product diameter up to 2 000 mm.

The list of forgings for gas turbines includes shafts of compressors and rotors, disks and rods, etc. 

The range of steels molten: 26CrNi3Mo2VA-A, 15Mo3, 26NiCrMoV145, 26NiCrMoV115, etc. We have solid experience of production of disks for gas turbines.

Forgings for rotors and disks for steam and gas turbines and turbine generator rotors, shafts and shells have been produced for more than 10 years at our facilities. Mastering the production of rotor forgings resulted in the development of technologies enabling to reach deformation processing of metal in the sections above 2 000 mm.

Elements and assembly units of high-pressure and low-pressure pipelines for thermal and nuclear power stations are made of both conventional steel grades used in energy industry and steels ensuring operation under supercritical conditions, including: St. 20, 15MnSi, 16MnSi, 17Mn1Si, 09Mn2Si, 10Mn2, 12Cr1MoV, 15Cr1Mo1V, 10Cr9MoVNb-ESR, 10Cr92MoVNbB, etc.

Estimated service life of pipelines for thermal power stations is 200 thousand hours:

  • discs, couplings, sleeve tubes, rotor and generator shafts;
  • stamped, stamp-welded and broached elbows;
  • T-fittings: stamped, forged, welded and with extended neck;
  • fitting connections and manifolds;
  • reducers: stamped, stamp-welded and welded; flat caps and stamp elliptic bottoms;
  • welded and flanged flow-measuring devises;
  • various types of flanges and fixing hardware;
  • pipeline supports and hangers; piping blocks.
