Maximize the life cycle of your rotor
Turbine rotors in gas and steam turbines are susceptible to various factors such as stress, fatigue, corrosion, embrittlement, or cracking, which can significantly impact their operational lifetime. Our lifetime assessment service is designed to identify and address these issues, helping to maximize the life cycle of your rotor.
Steam turbine maintenance and overhaul services typically include:
- Blade removal and reinstallation/reblading: Removing damaged blades and reinstalling new ones to maintain efficiency and performance.
- Stellite shield replacement: Replacement of protective stellite shields to prevent erosion and wear on turbine components.
- Diaphragm repair and replacement: Repairing or replacing diaphragms to ensure proper flow and pressure distribution within the turbine.
- Guide blade carrier repair: Repairing guide blade carriers to maintain alignment and stability of turbine blades.
- Impeller stacking: Stacking impellers to ensure proper assembly and alignment within the turbine.
- Cold and hot peening of tenons: Using cold or hot peening techniques to strengthen and repair tenons on turbine components.
- Machining: Turning and milling turbine components to achieve precise dimensions and surface finishes.
- Grinding: Grinding turbine components to remove surface imperfections and ensure smooth operation.
- Welding: Repairing disks and shaft areas through welding processes, including bearing journals, coupling fits, and seal areas.
- Complete disk rebuilds on integral rotors: Rebuilding integral rotors by replacing or repairing disks to restore functionality.
- Manufacturing of components: Manufacturing blades, diaphragms, shafts, rotors, and other turbine components as needed.
- Coating: Applying protective coatings to turbine components to enhance durability and performance.
- In-shop turbine disassembly/assembly: Disassembling and assembling turbines in a controlled shop environment to ensure proper maintenance procedures are followed.
- Low-speed balancing: Balancing turbine components at low speeds to minimize vibration and ensure smooth operation.
- At-speed balancing: Balancing turbine components at operational speeds to optimize performance and reliability.
- Field installation and start-up assistance: Providing support for installing repaired turbines in the field and ensuring proper startup procedures are followed.
- Advanced rotor restoration welding: Utilizing advanced welding techniques to restore damaged rotor components to their original condition.
Prevention is achieved by identifying and addressing the root cause.
When an incident occurs, understanding why it happened is crucial to prevent its recurrence. BBI can conduct root cause failure analyses for steam turbines to identify the underlying causes of failures and prevent future occurrences.
