TCS CO2 Cooling Pipe Inspection - Biannual

FAMIS27777

I didn't find any major issues with the pipes themselves, no leaks were found and the supports that were added last year (alog76528) seem to be helping. The flex joints still seem good and the plastic wrap around it also look OK. The same issues reported in the last inspection are still present (alog80015): cuts/scratches in pipes and a blocked outlet under HAM4 that also stressed the pipes there a bit from people pushing them out of the way to use the outlet. After getting Richard's approval, I moved the outlet up on its support beam and on a conduit support further down to clear the TCS pipes and relieved some of the stress on the pipes there - Pic1  Pic2
