We have been going through off-line spalling so that we had a chance to open the manhole to see what has been going on inside the column.
I have tried to post the image of collapsed tray but I couldn’t. If anyone leave his e-mail address,
I would love to discuss more about this problem.
Speaking of corroson, we have inspected the metal corrosion however, there was no evidence of any corrosion issue.
