Research on the Maximum Heat Dissipation Allowance in Insulation Design for Equipment and Pipes
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.
