Improved design of tube sheet sealing structure

Necessity of Improving Tube Sheet Sealing Structure Design
In chemical reactors, tube sheet seal failure can easily lead to leaks, affecting equipment safety. Traditional designs often suffer from uneven sealing surfaces due to thermal expansion or manufacturing errors, resulting in gasket extrusion and leakage. Improvements must consider both sealing reliability and operational convenience to adapt to high-temperature and high-pressure conditions.

Improvement Directions and Measures
Adopting a concave-convex flange sealing structure enhances the stability of gasket compression. Optimizing the connection between the tube sheet and flange reduces the impact of thermal stress. Introducing elastic compensation designs, such as bellows or expansion joints, mitigates seal failure caused by thermal deformation.

Improved Performance and Outlook
The improved sealing structure significantly reduces leakage rates, resulting in more stable equipment operation. Future research can explore intelligent monitoring technologies to provide real-time warnings of sealing status, further enhancing reactor safety and efficiency.
