: Applied to high-stress regions like shaft journals and thrust collars Severity B/C
API RP 687 applies to equipment manufactured to demanding API standards, including:
To define minimum requirements for inspections, repairs, and quality control, ensuring that repaired rotors meet original equipment manufacturer (OEM) or improved performance standards. If your organization utilizes a shared internal engineering
Adhering to API 687 during a rotor refurbishment ensures that high-speed rotating equipment is restored to a state of maximum operational reliability and safety. From incoming NDT to final precision dynamic balancing, every step must be executed with strict adherence to these established engineering principles. For any plant engineering or maintenance department, investing in an authorized, up-to-date copy of API 687 is an essential step in safeguarding equipment longevity and avoiding costly catastrophic failures.
To uncover hidden defects beneath the surface, a suite of NDT methods is deployed:
Addresses the extreme thermal environment of expander rotors, emphasizing material verification, specialized welding, and thermal coatings. Step-by-Step API 687 Rotor Repair Process API 687 provides strict guidance on acceptable repair
Shafts often suffer from worn journal areas or scores from bearing failures. API 687 outlines strict protocols for weld repairs:
: Repaired elements should meet performance requirements for a minimum five-year run.
A: All NDT personnel must be qualified in accordance with ASNT SNT-TC-1A . This includes written practices, defined Levels I, II, and III of certification, and specific training and experience requirements for each method.
