What is the design pressure that the pressure rupture disk blows out at in the air supply rack assembly?

The design pressure at which the pressure rupture disk blows out in the air supply rack assembly is specifically set at 8000 psi. This pressure threshold is crucial for the safety and operational integrity of the diving system. The rupture disk serves as a safety device designed to release excess pressure in the event that it exceeds safe operating limits, thereby preventing catastrophic failures and ensuring the protection of both the equipment and the divers relying on the supplied air.

Choosing 8000 psi reflects an understanding of the operational specifications and safety features incorporated into the design of the MK-20 / KM-37 Portable Surface Supplied Diving Systems. It underscores the importance of adhering to established safety parameters to avoid pressure buildup that could potentially lead to equipment malfunctions or risks during the diving operations.

Understanding this concept is vital for anyone working with such systems, as it ensures they can recognize safety thresholds and maintain proper operational procedures.
