摘要
P92钢作为新型耐热钢材料,常用于超超临界机组的高温、高压主蒸汽管道,其使用性能的优劣直接关系到机组的安全可靠运行。通过对P92钢的发展与研究现状进行分析,介绍了P92钢管检验的常用技术标准;并将P92钢与其他材料进行对比,提出了进口P92钢管检验过程中的常见问题;最后通过对比分析P92钢管检验常用技术标准的异同点,提出了进口P92钢管检验应注意的关键点。
As a kind of heat-resistant steel applied in ultra-supercritical units （USC）, P92 steel tubes are commonly used as main steam pipes of high temperature, high pressure and other components. Through analyzing the present development and research situation of P92 steel, the technical inspection standards for P92 steel tubes were introduced. The P92 steel and other materials were compared, so that the problems of P92 steel tubes during inspection were raised. Through the contrast analysis of similarities and differences of technical inspection standards of P92 steel tubes, the key points of inspection of imported P92 steel tubes were put forward.
