It is primarily used for non-destructive testing of pipelines, reactors, heat exchangers, pressure vessels, and various process equipment without the need for disassembly. It can quickly detect internal wall corrosion, cracks, coke deposits, scale buildup, and weld defects, significantly improving equipment inspection and maintenance efficiency, effectively preventing leaks and safety incidents, and greatly reducing downtime risks and repair costs. It serves as a crucial tool for ensuring the long-term safe operation of petrochemical facilities.
