API 687 Rotor Repair: A Guide to Standards and Procedures , titled Special-Purpose Rotating Equipment Repairs , is the definitive industry standard for the inspection and repair of critical turbomachinery components like rotors, bearings, and couplings in the oil, gas, and chemical sectors.
This initial assessment is conducted on the rotor as it arrives at the repair facility. It typically includes:
The primary goal of a repair performed under API 687 is to produce a safe, reliable rotating element that maintains its performance capabilities. Key objectives include: Api 687 Rotor Repair Pdf Download--------
Checking for obvious signs of erosion, corrosion, or mechanical damage.
Major erosion or corrosion should be repaired by welding, provided it is supported by a detailed "weld map" and documentation. API 687 Rotor Repair: A Guide to Standards
Generally, methods like plasma spray, metalizing, plating, or sleeving are prohibited for repairing bearing journals, seal areas, and impeller fits unless specifically authorized.
Now in its , this document provides the technical foundation for restoring equipment to "like-new" or improved condition, ensuring at least five years of uninterrupted operation . Key Objectives of API 687 Key objectives include: Checking for obvious signs of
If Phase I reveals major issues, the rotor is fully disassembled. Every individual component (impellers, disks, shafts) undergoes the same rigorous testing performed in Phase I.
Initial run-out and clearance measurements.
Minor damage—such as scratches or pits less than 0.005 inches deep—can often be resolved through polishing or blending. Why Compliance Matters API Recommended Practice 687, 2nd Edition
