The Process of Refurbishing Industrial Gas Turbine Parts: What to Expect?

Industrial gas turbines play a crucial role in various sectors such as power generation, oil and gas, and aviation. These turbines consist of numerous complex parts that need regular maintenance and refurbishment to ensure optimal performance and longevity. Refurbishing industrial gas turbine parts is a specialized process that involves thorough inspection, repair, and testing to meet stringent quality standards.

Understanding the Importance of Refurbishment

Industrial gas turbine parts are subjected to high temperatures, pressures, and rotational speeds during operation, leading to wear and tear over time. Refurbishment turbine parts by Allied Power Group helps in restoring these parts to their original specifications, improving efficiency, reliability, and safety. It also extends the overall lifespan of the turbine, reducing the need for costly replacements.

Initial Inspection and Assessment

The refurbishment process typically begins with a detailed inspection of the gas turbine parts to identify any signs of damage, erosion, or corrosion. Advanced techniques such as non-destructive testing (NDT) are used to detect internal flaws without compromising the integrity of the components. Based on the inspection results, a comprehensive assessment is made to determine the extent of refurbishment required.

Disassembly and Cleaning

Once the parts are identified for refurbishment, they are carefully disassembled from the turbine assembly. This step requires precision and expertise to avoid any further damage to the components. The parts are then thoroughly cleaned to remove contaminants, deposits, and surface imperfections. Specialized cleaning methods such as chemical baths, ultrasonic cleaning, and abrasive blasting are employed to achieve the desired level of cleanliness.

Repair and Restoration

After cleaning, the parts undergo repair and restoration processes to address any identified issues such as cracks, erosion, or dimensional deviations. Skilled technicians utilize techniques like welding, machining, coating, and thermal spray to restore the parts to their original condition. Advanced materials and coatings are applied to enhance the durability and performance of the components.

Quality Testing and Certification

Quality testing is a critical phase in the refurbishment process to ensure that the parts meet the required specifications and performance standards. Various tests such as dimensional inspection, hardness testing, dye penetrant testing, and balance testing are conducted to validate the integrity and functionality of the refurbished parts. Once the parts pass the rigorous testing procedures, they are certified for reinstallation.

Assembly and Reinstallation

After successful refurbishment and testing, the gas turbine parts are carefully assembled back into the turbine assembly following the manufacturer’s guidelines and specifications. Proper alignment, clearances, and torque values are maintained during the reinstallation process to ensure seamless operation. The refurbished parts are then integrated into the turbine system, ready to resume normal service.

Benefits of Refurbishment

Refurbishing industrial gas turbine parts offers several benefits to operators and industries. It helps in improving turbine efficiency, reducing maintenance costs, enhancing reliability, and extending the overall lifespan of the equipment. By opting for refurbishment instead of replacement, companies can achieve significant cost savings and minimize downtime associated with turbine maintenance.

Moreover, refurbishment contributes to environmental sustainability by promoting the reuse of existing materials and components, thereby reducing the demand for new resources and minimizing waste generation. 

Additionally, refurbishing industrial gas turbine parts often involves the integration of advanced technologies and materials, leading to performance enhancements and energy efficiency improvements. This not only benefits the operators by lowering operational costs but also aligns with broader sustainability goals. Furthermore, refurbishment can facilitate the adaptation of turbines to meet evolving industry standards and regulatory requirements, ensuring compliance while maximizing operational efficiency. Overall, the decision to refurbish turbine parts represents a strategic investment that yields long-term benefits for both the company and the environment.


In conclusion, the process of refurbishing industrial gas turbine parts is a meticulous and systematic approach that involves inspection, cleaning, repair, testing, and reinstallation. By following stringent quality standards and utilizing advanced technologies, refurbished parts can perform at par with new components, ensuring optimal turbine performance and longevity. Operators and industries can benefit greatly from refurbishment by maximizing efficiency, reliability, and cost-effectiveness in maintaining their industrial gas turbines.
