Checking if the rotor has been modified since it was originally built, ensuring new fits and clearances match updated design specs rather than solely the original design.
If Phase I yields evidence of mechanical trouble, a Phase II inspection is triggered. This is the phase where the rotor is unstacked (disassembled into its subcomponents) so that every single piece can undergo cleaning, NDT, and dimensional checks. The "No-Go" Repair Methods
Essential for flexible rotors operating above their first critical speed. This ensures the rotor safely traverses resonance zones without damaging labyrinth seals or bearings.

API 687 is a widely recognized standard for the repair and maintenance of rotors used in various industrial applications, including petroleum, petrochemical, and natural gas processing. The standard provides guidelines for the design, fabrication, inspection, and repair of rotors to ensure their reliability and performance. In this article, we will discuss the importance of API 687 rotor repair, provide a downloadable PDF guide, and outline best practices for rotor repair and maintenance.
What are you repairing? (e.g., centrifugal compressor, steam turbine)
A better repair involves you. Using your downloaded PDF, identify three mandatory witness points: Checking if the rotor has been modified since
When a critical centrifugal compressor or steam turbine suffers rotor damage, the financial stakes are massive. Production halts, and every hour of downtime bleeds revenue. In these high-pressure moments, maintenance managers and turbomachinery engineers often search the web for terms like hoping to find a quick, free document to guide their repair strategy.

is a Recommended Practice published by the American Petroleum Institute. Specifically titled "Rotor Repair," it standardizes the disassembly, cleaning, inspection, balancing, and reassembly of rotating machinery. The "No-Go" Repair Methods Essential for flexible rotors
A superior, "better" repair process goes beyond the minimum requirements, aiming for enhanced longevity, efficiency, and reliability. A. Comprehensive Inspection & Assessment
Industrial operators face a critical choice when a centrifugal compressor or steam turbine rotor suffers wear, erosion, or mechanical damage. You can choose a standard commercial repair to quickly return the equipment to service, or you can mandate compliance with the American Petroleum Institute’s .
