RLA Studies (Remaining Life Assessment)

Remaining Life Assessment (RLA) is a specialized evaluation process carried out to determine the safe operational life of critical industrial components operating under high temperature, pressure, and corrosive environments. RLA combines non-destructive testing, metallurgical examination, and operational data analysis to predict how long equipment can continue to function safely and reliably.

Applications of RLA Studies:

• Boilers, superheaters, and reheaters
• High-pressure and high-temperature piping systems
• Pressure vessels and storage tanks
• Turbines, compressors, and rotating equipment
• Chemical reactors and refinery components
• Critical parts in power plants, petrochemical, and process industries

Key Elements of RLA:

• Collection and review of service history and operating data
• Non-destructive examinations (UT, RT, PT, MT, hardness, thickness survey)
• Metallurgical testing (creep, fatigue, microstructure analysis, chemical analysis)
• Stress analysis and fitness-for-service assessment
• Prediction of remaining safe operating life
• Recommendations for repair, replacement, or continued operation

Standards Followed: ASME FFS-1 (Fitness-For-Service), API 579, ISO, IBR, and other international guidelines.

We provide comprehensive RLA Studies with certified reports, ensuring reliable decision-making for continued safe operation, maintenance planning, and cost optimization in sectors such as Power Generation, Oil & Gas, Refineries, Petrochemicals, Fertilizers, and Heavy Industries.
