Why is it important to ensure tubes project sufficiently into drums or headers?

Ensuring that tubes project sufficiently into drums or headers is primarily important for maintaining structural integrity. When tubes are correctly positioned within these components, they are better able to handle the thermal and hydraulic stresses encountered during operation. Adequate projection helps create a strong mechanical bond and minimizes the risk of tube movement or vibration, which could lead to wear or failure over time.

Inadequate projection can result in compromised strength at the joints, potentially leading to leaks or catastrophic failures. The structural integrity is crucial in maintaining the overall reliability and safety of the system, especially in high-pressure and high-temperature environments typical of marine applications. This reinforces the necessity for proper assembly and installation of the tubes into their respective drums or headers.
