FCT Augmentation Progress, O-ring Valve Installation
(Jordan V., Gerardo M.)
Late entry.
Last Tuesday Jordan and I installed 4 o-ring valves on the following crosses, FC-B2, FC-B4 and FC-B5.
Details, on FC-B2 we installed two o-ring valves, one on the +X 2.75" CF port, and the second one on the -X 2.75" CF port, both valves were tested for leaks, all new joints passed.
On the other two crosses, FC-B4 and FC-B5, we installed only one o-ring valve, one on each cross. The o-ring valves were installed on the +X 2.75" CF ports. Both valves were tested for leaks, all new joints passed.
