If there is a leak in the tubes of a shell and tube heat exchanger, what methods can be used to repair it and prevent further leaks?
What did I miss? Find a way to perform repair welding on the weld seam ； If there’s something inside the tube, it blocks the tube; it becomes useless ； Or replace the tube.

The tube that was leaking at both ends was sealed by plugs and welded shut, or a new tube was installed in its place
Perform a direct blind plug; if welding is required, it must be done properly. The key is to analyze the cause of the leak in order to come up with measures to prevent further leaks
Agree with what was said above; there’s no need to block it.
If patch welding is done, the welds on the surrounding pipes will crack again in just a few days
Is it better to use welding, or a plug? Previously, we sealed the leaky pipe, and it wasn’t an issue anymore, but after some time the welds around it cracked again
1. If corrosion is not the cause, the leaking pipe can be sealed. 2. If corrosion is the cause, a detailed analysis is required; replace the pipe and use different material
If it is a crack in the weld, it is recommended that you find the cause; plugging the pipe can only address leaks caused by defects in individual pipes. If the leak is due to corrosion or some other reason, it is advisable to identify the underlying cause.
