摘要

华能玉环电厂超超临界机组P92钢主蒸汽管道安装过程中

通过采取超声波纵波检测方法

可以有效检出管道端部存在的母材内部缺陷

消除主蒸汽管系存在的隐患

为保证机组安全稳定运行奠定了基础。

Abstract

In installing process of P92 steel main steam pipeline for the ultra-supercritical unit in Huaneng Yuhuan Power Plant

through adopting ultrasonic longitudinal wave detection method

the inner defects of raw material existing at ends of said pipeline can be effectively detected

laying a foundation for ensuring safe and stable operation of the unit.
