Leak detection of synthesis tower
Thread Content
At present, our plant’s synthesis towers have several leak detection channels, some of which are blocked; when using air for leak detection, almost no air comes out. What methods can be used to clear it? I hope fellow sailors can provide some guidance. Thank you!
The blocked pipes can be disassembled and cleared using air or nitrogen; the pressure can be increased appropriately, as long as it does not exceed 0.5 MPa. However, it is essential to control the pressure carefully to prevent overpressure. There is no better alternative, and the manufacturers of synthesis towers also use this method.
Additional note: Fill with nitrogen or an inert gas!
