“…Small‐bore piping systems are widely used in heat exchanger systems in which the water pressure and temperature are high, such as those in nuclear power and petrochemical plants and petroleum refineries. High cooling medium conditions promote the initiation and rapid propagation of cracks that degrade pipelines and threaten systems , making it necessary to inspect such cracks by using nondestructive testing (NDT) systems. As inspected pipelines are usually long and have small diameters, NDT systems such as a bobbin probes , motorized rotating pancake coils (MRPCs) , or X‐probes must be inserted; however, such NDT systems may be complicated (as is the case with MRPCs) or have low spatial resolution (bobbin and X‐probes).…”

This study proposes a method for the fast simulation of the distribution of alternating magnetic fields around internal cracks as well as cracks on the inner and outer diameter surfaces of a pipe. This method, which uses a bobbin‐type magnetic camera to inspect cracks in small‐bore piping systems, is based on a dipole model, allowing for the rapid calculation and storage of data on the distribution of alternating magnetic fields around cracks from a sensor moving inside a pipe.
