API Recommended Practice 687 (API RP 687)

, "Special-purpose Rotating Equipment Repairs," provides the minimum requirements for the inspection and repair of rotors, bearings, and couplings used in petroleum, chemical, and gas industry services.

• Inspection: Detecting wear, cracks, or imbalance using NDT methods (e.g., ultrasonic testing).
• Surface Treatment: Hardening or coating techniques (e.g., thermal spray) to restore component integrity.
• Balancing: Ensuring dynamic balance to prevent vibration.
• Shaft Straightening: Correcting deflection or misalignment.

: Provides rigorous standards for Non-Destructive Examination (NDE), including magnetic particle (MT), liquid penetrant (PT), and ultrasonic (UT) testing to detect defects in critical stress areas. Equipment-Specific Chapters Api 687 Rotor Repair Pdf Download--------
