scope:
IEEE Std 622A-1984 provides recommended practices for designing and installing electric pipe heating control and alarm systems as applied to mechanical piping systems that require heat. The recommendations include selection of control and alarm systems, accuracy considerations, local control usage, centralized control usage, qualification criteria of controls and alarms, and calibration and testing of controls and alarms.
Purpose
The purpose of this recommended practice is to provide recommendations that will ensure design consistency and reliable operation of electric pipe heating control and alarm systems which in turn will ensure that piping systems' fluids will be available for use not only during station operation but also during normal shutdown.
