Urgent help needed, please assist. Regarding the sealing issue.
Thread Content
Excuse me, I would like to make an opening at the top of the device’s flat cover for a pipe to extend through. This relates to the sealing issue. How can sealing be achieved, similar to a shaft and a hole? The pipe is roughly DN10. What are the methods?
Operating conditions: Medium, temperature, pressure, operating state (stationary, rotating, reciprocating)? The stuffing box will do
This is not easy to handle; it depends on factors such as pressure and the expansion rates of the two materials
The temperature is room temperature, and the design pressure is atmospheric pressure. The medium is somewhat corrosive. The extending tube is fixed in place and can be removed and secured from outside the flat cover. The pipes and flat cover holes need to be sealed; how should this be done?

1. A sleeve structure is a commonly used design.
Is the tube fixed inside the flat cover? If not, a welded structure can be used
If the pipe and flat cover can be welded, a welded structure is used; otherwise, a stuffing box structure is employed.
Selection is based on operating conditions and specific requirements, such as welding, threading, flanges, or stuffing boxes (dynamic sealing)
