Summary of Piping, Welds and Valves Not Subjected to a Pressure Test Following Installation and Justification for Not Pressure Testing
Item Rationale
EH-SSTR-PSV (Suction Scrubber Fire Case PSV)
Due to the sensitivity and complexity of the item/assembly, a field hydrotest would negatively affect the devices, components calibration or damage to the components.
No modifications were made to the assembly and/or single item after testing was completed.
Item has been shop (Manufacturer) tested and a field hydrotest is considered redundant to the shop test as it will not provide additional information.
