The measures used to prevent equipment or systems from exceeding their allowable pressure limits.
Overpressure Protection comprises the engineering measures, protective devices and operating controls used to prevent equipment or systems from exceeding their allowable pressure limits. These measures may include pressure relief devices, instrumented protective systems, process controls and operating procedures designed to protect personnel, equipment and the environment.
Overpressure Protection prevents pressure systems from exceeding safe operating limits and reduces the risk of equipment failure.
Effective overpressure protection is achieved through a combination of inherently safe design, pressure relief systems, instrumented safeguards, operating controls and maintenance programs in accordance with applicable engineering codes and standards.
Overpressure Protection encompasses all measures used to prevent excessive pressure, whereas pressure relief devices are individual components used to provide one form of protection.
