摘要：

分析了高合金耐热钢厚壁管道和锻件在电力工业中的应用情况和我国热挤压技术研究现状。结果表明，我国高合金耐热钢厚壁管道热挤压技术日趋成熟，应用范围不断扩大，但与之配套的技术标准研究与开发工作严重滞后。因此，国家标准《电站用高合金耐热钢厚壁管道和锻件通用技术条件》的研制具有必要性。介绍了该标准的技术概要，该标准规定了电站用高合金耐热钢厚壁管道和锻件的技术要求、试验方法、检验规则、订货内容及包装、标志和质量证明书，适用于热挤压或锻造工艺生产的电站用高合金耐热钢大口径（外径不小于Ф219 mm）厚壁管道和锻件。该标准的研制有助于提升电站用高合金耐热钢厚壁管道和锻件的产业竞争能力，有效服务于我国电力系统的基础设施建设。

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.
