New IEEE Standard - Inactive-Reserved. Recommended practices for designing, installing, and maintaining electric heat tracing systems are provided. 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.
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.
The purpose of this document is to provide recommendations that may be used in the design, installation, and maintenance of electric heat tracing systems as applied to mechanical piping systems. These recommendations are intended to ensure that the piping systems will be maintained at specified operating temperatures, which in turn will ensure that the piping systems' fluids will be available not only during station operation but also during normal and emergency shutdown.
