Certified Boiler Inspection & Maintenance

Fired boilers and process heaters operate at the boundary of high temperature, high pressure, and combustion, where tube failures and refractory damage can cause unplanned shutdowns, fires, and injuries. This course develops the knowledge required to inspect these assets effectively in accordance with API RP 573. Participants study corrosion and metallurgy in fired equipment, common heater and boiler designs, mechanical reliability, and the planning and execution of on-stream and shutdown inspections. Emphasis is placed on recognizing damage mechanisms, selecting appropriate inspection techniques, evaluating findings, and recording results that support repair and run-length decisions. Case studies drawn from refinery and petrochemical experience illustrate typical failures and lessons learned.

Who Should Attend

• Pressure equipment and fired equipment inspectors
