Rotor Reconditioning of Steam Turbine Generator

This project involved the rotor reconditioning of a steam turbine generator for a fertilizer producer in Southeast Asia, with the objective of restoring rotor integrity, improving operational stability, and supporting long-term equipment reliability. As a critical rotating component, the rotor required a controlled reconditioning process combining inspection, precision correction, targeted repair, and strict quality assurance. The work was carried out to reduce performance risk, address material degradation, and ensure the rotor could operate safely and consistently under demanding industrial conditions.

Scope of Work

• Perform Non-Destructive Testing (NDT) to identify micro-cracks, hidden flaws, and early-stage material fatigue
• Perform high-precision rotor balancing to ensure smooth rotation, reduce vibration, and stabilize long-term performance
• Perform targeted repair and reconditioning on worn-out areas through specialized machining, welding, and material restoration
• Apply multi-level quality control from initial inspection to final reinstallation
• Verify rotor condition and repair quality in accordance with strict quality protocols
• Support restoration of rotor reliability and operational performance
• Ensure readiness for safe and stable turbine generator operation
