API RP 687 is the definitive guide for disassembling, inspecting, repairing, and reassembling rotors used in pumps, compressors, and turbines. Unlike generic repair manuals, this standard addresses nuances specific to high-speed, high-energy rotating parts: bore inspection, weld repair limits, balance correction, and dimensional tolerances. A rotor repaired without adherence to API 687 may introduce undetected micro-cracks or imbalance, leading to unplanned downtime or dangerous in-service failures. Thus, the "repair" part of the keyword is inseparable from the standard itself.

The most direct and reliable source for API standards, including those related to rotor repair, is the official API website.
Most repair shops claim to follow API 687. However, there is a vast chasm between "claiming compliance" and "better compliance." Here are the three biggest failures of standard repairs: ❌ Avoid: 3-page summaries, PowerPoint converted to PDF,
To secure a superior PDF for rotor repair, follow this workflow:
API 687 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.
