Performance testing of tube sheets under high-pressure conditions

High-Pressure Sealing Test: Tube sheets require sealing performance testing under high-pressure conditions, including static pressure retention tests, to verify their leakage rate and stability under high operating pressure. The sealing integrity of the tube sheet's connections to the shell and heat exchanger tubes is evaluated through pressure decay and leakage rate measurements, ensuring no micro-leaks.

Strength and Deformation Monitoring: Hydraulic strength tests are conducted to monitor the structural deformation and stress concentration of the tube sheet under high pressure. Through visual inspection and stress analysis, it is ensured that the tube sheet can withstand the design pressure multiple, preventing plastic deformation or failure.

Environmental Simulation Verification: A high-temperature and high-pressure simulation chamber is used to test the long-term performance of the tube sheet under extreme operating conditions. Combined with acoustic emission detection, potential leakage points are located, verifying the reliability and durability of the tube sheet in a high-pressure environment.
