Pressure testing in a hermetically sealed tower
Thread Content
Which technician has newly installed equipment with full low voltage and argon? After installation, conduct a leak test. High and low voltage separated type. The main tower together with the argon tower. In addition to installing blind flanges at the inlet and outlet of the expander, blind flanges are also installed on the circulating argon pump. Do I need to add it at both the throttle valve leading to the tower and that leading to the crude argon condenser? Also, does it need to be added for nitrogen, oxygen, and contaminated nitrogen coming out of the tower? If anyone has experience with this, please share it
All areas that need to be isolated should be equipped with~~ Airtightness tests should be conducted; if everything is fine, then it’s okay. If there are issues, the process must be repeated from scratch, and the problems must be resolved~~
