Aiming at technology requirements of relevant welded pipe standards used for petroleum and gas pipeline project, in this article, it respectively provided probe display, sensitivity setting and specific detection methods of all kinds of defects in ultrasonic detection of steel plate and welded pipe. The type characteristics of various defects existing in the steel and welded pipe type were analyzed;the special probes used in ultrasonic detection were designed. It also introduced acceptance standard and application method. The usage of dedicated probes and special probes increased online detection efficiency, reduced material wastage, and ensured welded pipe quality.
