1.0 SCOPE
1.1 This standard covers the allowed methods of relief valve installation on vessels.
*
1.2 This standard is an adjunct to ST-1317 Relief Valve Policy.
1.3 Rupture Disk-Relief Valve combinations are covered in greater detail in ST-524.
1.4 This standard does apply to two rupture disks in series when all provisions of ST-524 have been met.
2.0 PURPOSE
2.1 To establish Group policy due to lack of complete clarity in the ASME code.
3.0 SOURCE
-
3.1 ASME Boiler and Pressure Vessel Code Section VIII, Paragraph UG-125 to UG-136, Addendum M.
4.0 DEFINITIONS
4.1 Valves are understood to mean hand operated shutoff valve either 2-port
\ or 3-port.
'
4.2 Relief "valves are understood to mean the reclosing-pressure relieving device.
4.3 Dual relief valves are two-relief valves of equal size and each capable of satisfying the vessel relief requirements.
5.0 INLET INSTALLATION
*'
5.1 The distance between the relief vafve and the vessel outlet nozzle shall be kept as short as possible. Direct connection is preferred.
5.2 Installations where dual relief valves (on one nozzle) are required for continued operation may have a -3-port'valve installed between the relief valves and the vessel outlet nozzle if the following conditions are met:
5.2.1 The valves and intervening piping must haye an area equal to the area of the inlet flange of the relief valve.
5.2.2 The valves must not be of top entering construction.

RELIEF VALVE INSTALLATION
ENG. STD.
ST-528 Sheet ? of r
0031 S/86
5.2.3
The pressure drop between the vessel and the intervening piping
and valve must not be greater than 3% of the set pressure of the
relief valves at full flow (See Sketch A). The relief valve must be set accordingly so'that the maximum pressure in the vessel cannot exceed the maximum allowable working pressure plus accumulation.
5.2.3.1 Alternate I may be used where the AP is less than 3% of relief valve set pressure to either valve.
5.2.3.2
Alternate II may be used-when the symmetrical arrangement cannot be used due to AP limitations. The pressure drop through the valve set at straight through flow must not exceed 3% of the relief valve setting.
5.3 Installations where multiple relief devices (on separate nozzles) are required-locking valves may be used between the vessel outlet nozzles and the relief devices, as follows:
5.3.1 -The installation shall be according to the sketch on page 6 of this standard. The lock shall be mounted to lock the valve in the
open position.
5.3.2 The valves and any spool pieces, if used, must have.an area equal to the area of the inlet flange of the relief valve.
5.3.3 The valve lock shall be Type KC/QKC as manufactured by CASTELL SAFETY, INC., specified to fit the particular valve to be used.
5.3.4 Only one key shall be furnished for each vessel/installation. The key shall be unique for that installation and shall operate all
locks. The key shall be captured upon opening the lock, which
allows the valve to be closed. This permits only one valve to be
closed at any one time--the others being locked open and the key
trapped at the closed valve. .* *
6.0 OUTLET INSTALLATION
* *'
6.1 Stop devices may be installed at the outlet of a relief valve if the valve discharges into a header j*ith other relief valves attached and it is necessary to continue operations. * The following conditions must be met:
6.1.1 Stop devices shall not have an area less than that of the relief valve outlet.

6.1.2 Stop devices shall be installed per Sketch B. The order of preference shall be I, II, III, IV. Operations of the vessel that is blanked must be shut down or a responsible person must be in attendance at all times the valve is shut or condition I, II, or
# III , exists. *
6.1.3 The*stop device roust be lockable in open or closed position.
6.1.4
The pressure drop must be calculated for all probable discharge
circumstances. The line
should not exceed 10% of set
pressure for standard relief valves or 50% of set pressure for
bellows type relief valves.
7.0 INLET AND OUTLET INSTALLATION
7.1 Valves or stop devices SHALL NOT be used on both the inlet and outlet of any relief device.
