This paper introduces the ultrasonic testing method of transverse wave testing simultaneously with the longitudinal combined probe of the parent material of the in-service pipe (medium diameter pipe) in the thermal power plant. It is proved that it has the characteristics of stable sensitivity, high efficiency and economy and practicality in theory and practice. It is an effective detection method to ensure the safe operation of thermal power plants and to improve the reliability and efficiency of pipe mastering.
