The middle joint of the distillation tower, which has been in use for half a year, is leaking! For some reason

Please clarify your question so that everyone can answer it

Generally, while driving, when the temperature of the equipment rises to a certain level, heating must be temporarily stopped to perform a \"thermal tightening\" of the equipment. I don’t know if your company has done it. Also, if it’s not there, then leaks may occur at the weak points of the gasket; at first, these leaks are not very noticeable. The later it gets, the harder it is to hold on. Actually, it’s your interface flange that’s damaged. During maintenance, the tower crane needs to be taken out of service, and the leaking areas at the interface should be welded shut. Additionally, anti-corrosion protection measures need to be applied again, in accordance with the technical requirements for the tower. Otherwise, problems will arise again in just a few days. Finally, don’t forget to tighten it up while driving. The above are purely personal opinions! This post was last edited by www557 on 2009-3-5 10:33]

1 It should not be a leak caused by corrosion. Check the drawings to see if there are any issues with the selection of the 2 gaskets. 3 interfaces: check for any defects on the flanges. Has there been any change in the operating conditions of Process 4, and are they consistent with those specified by the manufacturer of the tower?

It might be a structural issue; it shouldn’t be a stress-related problem

Did you conduct a stress analysis at that time/? 1 Unreasonable in design 2 May be a fatal flaw

Improper selection of gasket material or type； Or the gasket is damaged ； The connection bolts are not tightened properly ； The flange sealing surface has poor quality or is damaged
