ajst-16342	Yang, Xiaonan	Brief Discussion on Non-destructive Testing Methods for Pressure Pipeline Defects	2024	3	.pdf	application/pdf	2082	94	50	Laser holographic detection Laser holographic detection is a new detection technology used in the detection of pressure pipeline defects, which uses laser holography to detect the surface or internal defects of pressure pipeline. Magnetic Particle Detection The application of magnetic particle detection technology in the detection of pressure pipeline defects is to make use of the fact that the pipeline defects are different from the magnetic resistance of the pipeline material, and the magnetic field line passing through the pipeline will bend at the pipeline defects and may escape from the pipeline surface, thus forming a leakage magnetic field.	cache/ajst-16342.pdf	txt/ajst-16342.txt
