The maximum pressure at which a pipeline or pressure system may be operated safely under specified conditions.
Maximum Allowable Operating Pressure (MAOP) is the highest pressure at which a pipeline or other pressure system is permitted to operate under normal service conditions. It is established in accordance with applicable design codes, regulatory requirements and engineering assessments to ensure safe and reliable operation throughout the asset's service life.
Maximum Allowable Operating Pressure defines the highest permitted operating pressure for a pressure system during normal service.
MAOP is commonly applied to pipelines and transmission systems and may be limited by design, testing, material properties, operating history or regulatory requirements.
Maximum Allowable Operating Pressure defines the highest permitted operating pressure during service, whereas Maximum Allowable Working Pressure is the design pressure limit of a pressure vessel or component.
