Turbine Blend, Polish, Peen Services
Precision Turbine Rotor Repair and Surface Enhancement
Comprehensive Turbine Rotor Repair and Coating Services
Advanced Turbine Support delivers expert turbine blend, polish, and peen repair services for gas turbine, steam turbine, and aeroderivative applications.
Our team provides both field service and in-shop overhaul programs tailored to OEM specifications, extending the life of your critical turbine components while improving performance and corrosion resistance.
Whether you operate a GE 7F, 7FA, or 9F series unit, our technicians perform advanced rotor management and turbine blade restoration using proprietary polishing processes and precision coating systems.
The Turbine Blend, Polish, and Peen Process
Our blend, polish, and peen (BPP) procedure restores the edge condition and surface integrity of turbine wheels, discs, and rotors.
The process is engineered to meet manufacture specifications, prevent crack initiation, and minimize stress concentration in high nickel alloys commonly found in F-class turbines.
-
Blending: Technicians reshape and remove surface imperfections, providing an ideal radius along cooling slots and dovetail edges.
-
Polishing: Each surface is refined to a mirror-like finish that enhances coating adhesion and reduces the likelihood of crack propagation.
-
Peening: Using advanced flapper peening methods and the latest technology, compressional forces are applied to strengthen the surface layer and mitigate initiation of fatigue.
All steps are verified using penetrant inspection and fluorescent NDE methods to confirm full coverage and eliminate subsurface indications before final approval.
Turbine Rotor Management and Overhaul Capabilities
Advanced Turbine Support combines rotor management expertise with advanced diagnostics and manufacture-grade repair services.
Our goal is to extend the life of your rotor through systematic inspection, maintenance, and refurbishment.
We perform:
- In-situ inspection and surface diagnostics for compressor and rotors
- Disc and dovetail slot restoration using precision blast and polish systems
- Application of HVOF or thermal coating solutions to protect against corrosion and high temperatures
- Full overhaul services with balance, runout, and alignment verification
Each engine is supported by research and development data from our long-term supplier network, ensuring compatibility across your entire fleet of gas turbines.
Polishing and Coating Processes for Power Generation
Our proprietary polishing processes ensure every blade, vane, and disc achieves a flawless aerodynamic finish.
These treatments help operators rotate units more efficiently, reduce downtime, and maintain consistent power generation output.
Surface Enhancement Services
- Mirror-like polish for turbine and compressor components
- Protective coatings to guard against oxidation and thermal stress
- Dovetail slot conditioning for smoother transitions and stress relief
- NDE methods and diagnostics to confirm edge geometry and capability
- Maintenance recommendations aligned with OEM and PSM standards
By combining polishing and coating technologies, we provide a complete repair solution that improves reliability while reducing life-cycle cost.
