IEEE 622-1987 IEEE Recommended Practice for the Design and Installation of Electric Heat Tracing Systems for Nuclear Power Generating Systems

IEEE 622-1987 IEEE Рекомендуемой практики по проектированию и монтажу электрических извещений тепла для создания ядерно-энергетических систем

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.
