Define 'maximum allowable operating pressure' (MAOP) in gas systems.

The concept of 'maximum allowable operating pressure' (MAOP) in gas systems is crucial for ensuring safety and operational integrity. MAOP is defined as the highest pressure at which a gas system can be safely operated without risking a failure or catastrophic event. This pressure is determined based on various factors, including the design and materials of the system, safety factors, and regulatory requirements.

Setting the MAOP is essential for protecting the system from overpressure situations that could lead to leaks, ruptures, or other failures. Engineers calculate this value during the design process to ensure that all components of the system can withstand the pressures they will encounter, alongside accounting for potential pressure fluctuations during operation.

Understanding MAOP is vital for anyone working in gas systems as it helps maintain safety standards and compliance with regulations.
