IEEE 622A 84th Edition, January 1, 1984 Recommended Practice for the Design and Installation of Electric Pipe Heating Control and Alarm Systems for Power Generating Stations (Supplement to ANSI/IEEE Std 622-1979, IEEE Recommended Practice for the Design and Installation of Electric Pipe Heating Systems for Nuclear Power Generating Stations)
More info
Description / Abstract:
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.
