Abstract：

The application of high alloy heat-resistant steel thick wall pipes and forgings in the power industry and the current status of research on hot extrusion technology in China were analyzed. The results show that the hot extrusion technology of high alloy heat-resisting steel thick wall pipes in China is becoming more and more mature, and the application scope is expanding, while the research and development of the matching technical standards are seriously lagging behind. So it is necessary to develop the national standard GB/T 41982—2022 High alloy heat-resisting steel thick wall pipes and forgings used for power station—General specification. The technical summary of the standard was introduced. The standard specifies the technical requirements, test methods, test rules, ordering content as well as packaging, marking and quality certification of high alloy heat-resisting steel thick wall pipes and forgings used for power station, which is applicable to the large diameter (outside diameter of not less than Ф219 mm) and thick wall pipes and forgings of high alloy heat-resisting steel used for power station produced by hot extrusion or forging process. The research of the standard is helpful for enhancing the industrial competitiveness of high alloy heat-resisting steel thick wall pipes and forgings for power stations, and plays a positive role in the infrastructure construction of power system in China.
