API Releases Fourth Edition of RP 576, Inspection of Pressure-Relieving Devices

The American Petroleum Institute recently released an updated Fourth Edition of API RP 576, Inspection of Pressure-Relieving Devices. This recommended practice (RP) describes the inspection and repair practices for self-actuated pressure-relieving devices commonly used in the oil/gas and petrochemical industries. As a guide to the inspection and repair of these devices in the user’s plant, it is intended to ensure their proper performance. This publication covers self-actuated devices such as direct-acting spring-loaded valves, pilot-operated pressure-relief valves, rupture disks, pin-actuated devices, and weight-loaded pressure vacuum vents. 

This RP does not cover training requirements for personnel involved in the inspection and repair of pressure-relieving devices. Those seeking these requirements should see API 510 and API 570, which give the requirements for a quality control system and specify that the repair organization maintain and document a training program ensuring that personnel are qualified.
