摘　　要：《设备及管道绝热技术通则》(GB/T 4272)是保障我国工业设备及管道工况运行和节能降耗的重要基础性国家标准,已发布实施40余年,现行版本为2008版,被国内60余项国家标准规范、行业标准所引用。标准中给出的常年和季节工况运行最大允许散热损失量是石化、电力、冶金等行业进行设备及管道绝热设计时的重要基础参数,也是绝热工程施工、验收及绝热效果测试评价的重要依据。该标准被列入2022年国家双碳标准专项计划,已于2024年1月顺利通过审查会。本文详细介绍了GB/T 4272修订工作中对最大散热损失量的研究和分析,阐述了最大允许散热损失量的修订方案的确定依据和过程。GB/T 4272 "General Principles for Thermal Insulation Technique of Equipment and Pipes" is a crucial foundational national standard for ensuring the operation and energy conservation of industrial equipment and pipeline conditions in China.Having been implemented for over 40 years,the current version dates back to 2008 and has been referenced by more than 60 domestic national standards and industry norms.The maximum allowable heat dissipation under normal and seasonal operating conditions,as specified in the standard,serves as a significant parameter for insulation design in industries such as petrochemicals,power,and metallurgy.It also plays a vital role in the construction,acceptance,and insulation effectiveness testing and evaluation of insulation projects.This standard has been included in the 2022 National Dual Carbon Standards Special Plan and successfully passed the review meeting in January 2024.This paper provides a detailed presentation of the research and analysis conducted during the revision of GB/T 4272,focusing on the determination basis and process for the revision of the maximum allowable heat dissipation.
