[@سوسو-ه9ث]

Thank you Mr. Eric for sharing like this kind of videos. we would like to watch more of your real work videos

[@MrEric_API]

Arif, my plan is to keep making videos. Tell everyone, and let's hear what kind of subjects are of interest.

Is this pre cleaning inspection? The brownish deposits on the shell, are they process deposits

[@MrEric_API]

Andy, this is the base metal as found. No progress debris was present.

hi mr eric, What types of corrosion found in the heat exchanger shell?

[@MrEric_API]

This corrosion was mainly MIC type corrosion. samples of the corrosion and process debris was taken and tested for the presence of biological colonies, it was VERY high. Mr Eric

That 1” or 1.5” threaded nozzle attachment weld(at the end of this vid) is all but gone. Was it recommended for a repair?

[@MrEric_API]

1" with a plug. I recommended replacement of the entire shell assembly....... I believe it was returned to service, with a new bundle.

[@wakeupbeb]

what is your recommendation??

[@MrEric_API]

The vessel runs at 20 psig, in a bank of double-fours. It comes out of service every other year. I recommended to look at it @ the next OOS interval. I don't expect the corrosion to be any different, though time will tell.

@@MrEric_API to be monitor ?

[@wakeupbeb]

@@MrEric_API hello mr eric.. can your tech us how to calculate pitting and thinning on vessel.. how to do it

[@MrEric_API]

@@wakeupbeb I'll add it to the list of upcoming video content. MrEric

what kind of liquid would have been in something like this?

[@MrEric_API]

Jolly, this exchanger did have versions of oil on both sides. The sides being the tube and then the shell (that's what your seeing in this video) This is used commonly to use a hot liquid that they need to cool to heat up an incoming colder liquid. In this case the hotter liquid is on the shell side, heating up the tubes and the colder liquid in them.
