Flow system

1. Rotor’s repairing
   • blades replacement
   • sealing sheets replacement
   • regeneration of journal bearings
   • non-destructive tests
   • appraising the degree of wear and giving guidance for further exploitation
   • final mechanical working
   • in exceptional cases rebuilding of blade edges

    

2. Turbine diaphragms and nozzles
   • degree of wear appraising
   • weld regeneration
   • rebuilding of blade edges
   • sealing replacement
   • final mechanical working
   • guidance for further exploitation

    

3. Nozzle boxes
   • degree of wear apprising
   • defect removing
   • revitalization (material structure regeneration)
   • welding repairs
   • mechanical working and components assembly
   • guidance for further exploitation

Hulls and stuffing boxes

• degree of wear apprising
• defect removing
• revitalization (material structure regeneration)
• welding repairs
• mechanical working and components assembly
• guidance for further exploitation

Valves and servomotor overhaul

• valve elements regeneration (e.g. diffusers, sleeves)
• manufacturing new components, including stellites and CRC (chrome carbide) coating
• motion and pressure tests (creating of motion characteristics)
• degree of wear apprising and revitalization of valve chamber casings
• welding surface regeneration
• final mechanical working
