Experimental Study on Microwave NDT of Metal Pipeline Surface Defects

AbstractIn this paper, a new method for defecting and locating the surface defects in the metal pipeline by microwave technology is proposed. Through setting up the microwave NDT system, the impact of metal pipeline surface defects on the microwave transmission characteristics is studied. Finally, the non-contact defection and location of pipeline defects are realized and the influence of microwave field caused by pipeline surface defects is obtained through this system. The conclusion can provide basis for metal pipeline surface defects locating and safety assessment.KeywordsReflection CoefficientDefect SizeDefect LocationInsertion LossMicrowave FieldThese keywords were added by machine and not by the authors.
