The impact of tube sheet machining accuracy on assembly

Accuracy and Assembly Fundamentals: Tube sheet machining accuracy directly affects assembly quality. For example, errors in tube hole spacing and perpendicularity can lead to loose connections between tubes and the shell, increasing the risk of leakage. High-precision machining reduces error accumulation, ensuring smooth component fitting and improving overall equipment reliability.

Error Accumulation Effect: If the tube sheet hole position deviation is too large, additional adjustments are required during assembly, which may lead to stress concentration and reduce equipment lifespan. Especially in the aerospace field, even small errors can be amplified into system failures, affecting heat exchange efficiency.

Quality Control Key Points: Strict tolerance control, such as optimizing the drilling process, can significantly improve assembly accuracy. This not only simplifies the assembly process but also enhances the equipment's stability in high-temperature and high-pressure environments, making it suitable for critical components in chemical and aerospace applications.
