本文件提供了设计和安装核电站电伴热系统的推荐做法。这些电伴热系统应用于输送含硼水、烧碱和其他溶液的机械管道系统，用于关键工艺温度控制和工艺温度控制。电伴热系统也应用于水管系统，以防止它们在寒冷天气下结冰。建议包括确定要求、加热器设计考虑因素、电力系统设计考虑因素、温度控制考虑因素、警报考虑因素、完成的图纸和文件、材料安装、启动测试、温度测试以及电管道加热系统的维护。

This document provides recommended practices for designing and installing electric heat tracing systems in nuclear power generating stations. These electric heat tracing systems are applied, both for critical process temperature control and for process temperature control, on mechanical piping systems that carry borated water, caustic soda, and other solutions. Electric heat tracing systems are also applied on water piping systems to prevent them from freezing in cold weather. The recommendations include identification of requirements, heater design considerations, power systems design considerations, temperature control considerations, alarm considerations, finished drawings and documents, installation of materials, startup testing, temperature tests, and maintenance of electric pipe heating systems.
