Part 4 Machinery and Systems
Chapter 2 Pumps and Piping Systems
Section 1 General
7.15 Relief Valves
All systems which may be exposed to pressures greater than that for which they are designed are to be
safeguarded by suitable relief valves or the equivalent, and pressure containers such as evaporators,
heaters, etc., which may be isolated from a protective device in the line are to have such devices either
directly on the shell or between the shell and the cut-off valve.
7.15.1 Exceptions
In pumping systems such as boiler feed, oil piping and fire main, where ordinarily relief
valves are required at the pump, such valves need not be fitted when the system is served only
by centrifugal pumps so |
