Pressure Relief Systems

摘要

Pressure relief valves (PRVs) help ensure the reliability of equipment, help plants maximize output and help control operating costs. They also are crucial safety devices, typically serving as the last line of defense in an overpressure situation, protecting equipment, facilities, products and people. Personnel who do not understand a valve's function cannot be expected to make it operate consistently at peak performance. Those responsible for plant maintenance and operation must be properly trained and knowledgeable in pressure relief systems and how operational decisions affect a valve's maintenance cycle. Plant maintenance personnel should consult maintenance manuals - and an experienced valve technician - in developing and executing an ongoing maintenance program.
