According to regulations, what is the minimum design pressure required in a distribution system?

The minimum design pressure required in a distribution system is critical for ensuring safety and efficiency in various applications, particularly in gas distribution systems. A minimum design pressure of 30 psi is established based on regulatory guidelines that account for factors such as the maximum operating pressure, the need to accommodate pressure variations, and ensuring that the distribution system can handle potential pressure drops during peak usage.

This specification is designed to prevent issues related to insufficient pressure, such as gas flow interruptions or the inability to properly deliver the service to end-users. Furthermore, the regulations often consider the need for a buffer above normal operating pressures to account for potential surges or fluctuations, reinforcing the requirement for a minimum design pressure of 30 psi as a standard practice to enhance reliability and safety of the system.
