This method has helped us eliminate the hidden troubles of the main steam pipework, therefore, a foundation has been laid for&nbsp; the safe and stable operation of the units. <br/>[Keywords] Ultra-supercritical, detect, P92 steel, main steam pipe, raw material defects&nbsp;&nbsp;<br/>&nbsp;</font></p>
