Steam turbine monitoring
Steam turbine vibration monitoring and protection: Bently Nevada 3500, axial position and overspeed channels, SDT ultrasound for steam traps and auxiliary equipment.
Steam turbines: API 670 protection
Steam turbines are the core of thermal units. Unplanned trips mean lost generation and long repairs. In Kazakhstan and CIS plants, Bently Nevada 3500 with 3300 XL remains the protection standard.
Protection stack
- Radial vibration and axial position modules
- 3500/53 Overspeed
- Historization in System 1
- SDT/TRAPChecker for traps and auxiliaries
Olympus — flow-path RVI and piping thickness
On outages, add remote visual and thickness gauging:
- IPLEX videoscopes — flow path and cavities without full tear-down (IPLEX One, IPLEX NX); model guide — which IPLEX to choose
- Thickness gauges — steam lines and vessels (39DL PLUS); practice — pipe corrosion on CHP and refineries
Industry: power generation vibration.
