Reliability design of tube sheet and flange connections

Design Principles
The connection between the tube sheet and flange must consider sealing performance, strength, and thermal stress adaptability. The design prioritizes matching the flange type with the tube sheet structure to ensure a stable connection under high temperature and pressure, preventing leakage or deformation.

Key Measures
Using raised-face flanges enhances sealing reliability, and optimizing the welding process reduces the impact of thermal stress. For conditions with large temperature differences, elastic compensation structures (such as bellows) are introduced to mitigate thermal deformation and improve connection durability.

Application Effects
A rational design significantly reduces the risk of leakage and extends equipment lifespan. In the future, combining this with intelligent monitoring technology can provide real-time warnings of connection status, further optimizing the operational safety of equipment in chemical, energy, and other fields.
