摘要
Abstract
Thermal insulation is affixed to the exteriors of water and steam pipelines in power plants to enhance heat exchange efficiency.Conventional ultrasonic and guided wave inspections are the primary methods used for testing ferromagnetic pipelines.Before these tests can be performed,the insulating layer on the outer surface of the pipeline must be removed—a cumbersome process that increases both inspection time and costs.Pulsed eddy current(PEC)inspection can rapidly screen pipelines without necessitating the removal of the insulation layer.The inspection coil design and sensitivity rate are critical indices for PEC testing.Utilizing the Maxwell module in ANSYS for component modeling and simulation,this study contrasts results from coaxial and vertical inspection coils to determine an optimal design and examines PEC sensitivity.The efficacy of these methodologies is verified using test blocks,culminating in a discussion on prospective advancements in PEC technology.关键词
