Application of Ultrasonic Phased Array Technology in the Inspection of Small Diameter Pipe Welds on the Heating Surface of Circulating Fluidized Bed Boilers

Abstract As a new type of testing technology, ultrasonic phased array technology can achieve the efficiency and quality that other methods cannot achieve. This paper gives comprehensive overview application in inspection small diameter pipe welds circulating fluidized bed boiler, analyzes difficulties process, summarizes possible non-relevant indications generated by array. provide reference for detection boilers has practical significance relevant research technology.
