Air seal issues in low-temperature recovery circulation pumps
Thread Content
For sealing the circulation pump in low-temperature recovery processes, we currently use a very small amount of the finished 98% acid for this purpose. These days, there is a sand hole in one of the 15-grade stainless steel pipes, which is causing acid leakage; despite wrapping it with PTFE tape, the leak persists. If we switch to using compressed air for sealing, it will be necessary to stop the machine due to the high pressure. Do you think it would be feasible to use compressed air for sealing?
Moderator: I’ve read it twice but still don’t understand what exactly you’re trying to say???
OP: Use an air seal; I’ve already suggested to Ogil that he use this method, and it should have no impact on the equipment. At least it has no impact on our setup.
