Title : Enhancing asset integrity through online gamma scanning and radioactive tracer technologies for non-intrusive inspection
Abstract:
Maintaining the integrity of process equipment is essential for ensuring safe, reliable, and efficient plant operations. Conventional inspection methods often require equipment shutdown, isolation, and intrusive internal access, resulting in production losses, increased maintenance costs, and extended outage durations. This paper presents the application of Online Gamma Scanning and Radioactive Tracer technologies as advanced non-intrusive inspection solutions that enable equipment assessment while facilities remain in normal operation. Gamma Scanning evaluates internal equipment conditions by measuring density variations using a controlled gamma radiation source and detector, allowing the detection of flooding, fouling, internal blockages, hidden leaks, mechanical damage, and process maldistribution. Radioactive Tracer technology complements this approach by identifying flow paths, locating leaks, detectin restrictions, and evaluating process performance within piping systems without interrupting production.
The implementation of these online inspection techniques provides accurate diagnostic information while eliminating many of the limitations associated with conventional shutdown inspections. By reducing the need for intrusive activities, these methods improve inspection efficiency, enhance personnel safety, and support informed maintenance decisions based on actual equipment condition. Field applications have demonstrated inspection cost reductions exceeding 50% and approximately 30% reduction in shutdown inspection scope while maintaining equipment reliability and process availability. These technologies represent practical solutions for modern asset integrity management, helping operators optimize inspection strategies, improve operational reliability, and maximize asset availability.
