The Applied Technical Services Family of Companies (ATS FoC) provides steam turbine inspection services to our clients in power generation, petrochemical, pulp and paper, oil and gas, nuclear energy, and other industrial facilities to help identify steam turbine defects early before they escalate to costly failures and safety hazards.
Steam turbines are essential to energy production. They convert high-pressure steam into mechanical energy for efficient electricity generation and industrial applications. Our specialized inspections assess the condition, performance, and service life of steam turbines and their components to help prevent unplanned outages and support safe, reliable operation.
What Components Are Usually Inspected During a Steam Turbine Inspection?
We focus our inspections on the most critical internal and external components that impact steam turbine performance, such as:
- Blades, Bearings, and Buckets
- Generators and Compressors
- Rotors and Shafts
- Valves and Control Systems
- Bolting and Fasteners
- Casings and Seals
- Pumps, Filters, and Lubrication Systems
- Steam Piping Connections
Advanced Methods for Defect Detection
At ATS, our steam turbine inspections typically begin with a review of operating data, followed by visual or borescope inspections to identify early signs of component wear, corrosion, cracks, or performance issues. During planned outages, our certified level II and III inspectors use advanced inspection techniques and non-destructive testing to assess the structural integrity of critical turbine components. We also look for signs of lubrication issues, misalignment, leakage, vibration, and overheating. Based on key findings, we deliver clear data reports to guide and support maintenance and/or repair decisions.
Common methods for detecting steam turbine defects include:
- Eddy Current Testing (ET)
- Magnetic Particle Testing (MT)
- Liquid Penetrant Testing (PT)
- Ultrasonic Testing (UT)
- Phased Array Inspections
- Borescope Inspections
- Fluorescent Penetrant Inspections
- Vibration Analysis
- Oil Analysis
What Standards are Applied During Steam Turbine Inspections?
While the applicable standards applied depend on the inspection method, turbine design, and project scope, we typically perform steam turbine inspections in accordance with:
- ASME (Section V, Section XI, B31.1)
- ASTM (ET, MT, PT, UT)
- ASNT (SNT-TC-1A, CP-189)
- OEM-Specific Requirements from Turbine Manufacturers (Siemens, Mitsubishi, and Alstom)
We tailor our steam turbine inspection services to meet your specific project requirements.
