What is another method of overpressure protection for heat exchangers?

A rupture disc serves as an effective method of overpressure protection for heat exchangers because it is designed to provide a one-time solution that quickly relieves excess pressure within a system. When the pressure exceeds a predetermined limit, the disc ruptures, allowing the contents to escape safely and preventing damage to the heat exchanger or other connected equipment.

This method is particularly beneficial because it operates without any moving parts, resulting in a reliable and almost instantaneous response to excessive pressure. It's commonly used in situations where rapid pressure relief is necessary to maintain system integrity while minimizing the risk of hazardous situations or equipment failure.

In contrast, other options like safety valves and pressure relief valves, while also important for pressure management, generally involve moving parts and might not react as quickly as a rupture disc in specific conditions. Overflow pipes are typically utilized to manage fluid levels rather than directly protect against overpressure scenarios. Thus, a rupture disc is highlighted for its unique attributes that make it suitable for protecting heat exchangers against overpressure situations effectively.
