Pressure testing issue of the horizontal tube primary cooler
Thread Content
When pressurizing the tube bundle of a horizontal tube primary cooler, is it done by first pressurizing the shell side and then the tube side? Exactly how to do it, and what to do when defects are found
If the flaws in the pipeline development are not addressed, pressure control will become a serious issue, and dealing with it is even more troublesome than installing new components!
We tried to repair the leak, but it leaked again soon after; we gave up and decided to replace it with a new one
Don’t put the tube side head on first; pressurize the shell side – if the pressure cannot be maintained, use a piece of paper or something else to determine which part is leaking
I have a question: if there is a leak at the junction where the pipe fitting meets the tube sheet, can it be repaired by welding? I’m worried that Mars will fall down, because the pre-cooler is only purged with nitrogen and not cleaned
When testing for leaks in the primary cooler, using pressurized gas is the most straightforward method. Leaks in the primary cooler usually occur in the horizontal tubes; fixing minor leaks in the cooling tubes is also simple – just plug them with a nylon rod
