Stone clogging in the tube bundle of a fixed-tube-sheet propylene heat exchanger
Thread Content
There is debris blocking the tubes in the propylene fixed-plate heat exchanger of my company, and even after cleaning with a high-pressure water gun, the debris has not been completely removed; some pieces of debris are still present inside the tubes. I would appreciate it if fellow sailors could offer some valuable suggestions regarding effective methods for removing this debris. Thank you very much! ! ! !
Use an impact drill bit with an extension rod to drive it.
Try using diluted salt and acid bubbles:lol:lol
