Appendix 4: Pressure relief
11.1
Pressure rating of pump housings and Single-Use Devices
The XCell ATF® Device stainless steel pump housings are designed and 100% hydrotested and ASME
U Code stamped to a maximum allowable working pressure of 45 PSIG at 300 F. Stainless steel
assemblies are pressure tested (hydrostatic pressure test at 70 PSIG) and marked in accordance with
the ASME Boiler and Pressure Vessel Code. XCell ATF® Single-use Devices are designed and validated
to withstand a maximum allowable working pressure of 50 PSIG at 40
o
C. All Single-use devices are
subjected to an integrity test pressure hold of 325 PSIG as part of standard release testing.
11.2
Overpressure relief
To protect the XCell ATF® Device housings and devices from reaching pressures > 40 psig, a pressure
relief assembly set at 40 PSIG is located on the outlet of pneumatic box supplying pressure and
vacuum to the air-side hemisphere of the pump housing. The flow path of pressure relief is shown
below.
