Boiler`s Tube Assessment and Repair Optimization

This paper discuses assessment and repair methodology for the Boiler tubes. The subject boiler experienced defective tubes that impacted its operational efficiency. Defective tube presence had a significant effect on Boiler reliability and would lead to operational failure if it was not appropriately maintained. Interrelated chronic issues required a systematic analysis to identify the optimum repair methodology. The impacted Boiler was evaluated through life assessment procedure and recommended to be re-tubed. A specific repair procedure was proposed to tackle this failure. Feasibility and cost-effectiveness of the Boiler settlement, age, and structural durability was considered while repairing this equipment. As a result, both reliability and maintainability have been enhanced following re-tubing project completion addressing all defective tubes and returning equipment back to operation.
