@georgeverghese:
There was no tube leakage and no tube clogging. Our cooler problem was that the LMTD was increasing, the acid temp on the shell side outlet was increasing. That’s was why we would like to know what happened inside of the shell side.
@EdStainless:
We'd had think about the video borescope too. But currently we only had a short probe, while our cooler was about 10 meters across the shell side length. We need to seek steerable borescope with at least 15~20 meters probe length.
Alternatively, we would like to know the...
@georgeverghese:
That is also one possibility that cause increasing of the LMTD.
If possible, we would like to know any kind of non destructive inspection method that did not require physically damaging the cooler parts.
Hello !
We had an unused Sulphuric Acid Cooler, a horizontal fixed tubesheet Shell & Tube type. It was used to cooling down the circulated Sulphuric Acid liquid on its Shell Side. Sea water was the coolant on its Tube Side. This cooler operation time was relatively short since it was installed...
