An Applied Study on Eddy Current Array Testing Technology for Transportable Pressure Vessels

Abstract To solve the problems with the penetrant testing of transportable pressure vessels (“TPVs”), such as failure to detect near-surface defects, low testing efficiency, and damage of penetrating agents to testers’ health and the high-purity media in the TPVs, an experimental study on the eddy current array (“ECA”) testing technology is carried out, and the result is compared with the results of the dye penetrant testing and fluorescent penetrant testing. According to the experiment result, the ECA testing technology is characterized by moderate requirements for the status of the surface to be tested, fast testing, environmental-friendliness, electronic data storage, testing imaging, and accurate testing results. These advantages enable the ECA testing technology to be a green and environmental-friendly nondestructive testing technology that will promote future development and have exciting prospects in TPV testing.
