Pressure 관련 용어 Operating Pressure : Equipment 또는 Pipe의 Normal Operation 동안 나타나는 Pressure Design Pressure : 설계시 목표로서 잡는 압력. Operating 시 가장 Severe 한 Condition을 Cover 하는 기준으로 결정한다.
PSV가 설치되는 Pipe의 Engineering Spec.으로 보면 된다. MAWP : Maximum Allowable Working Pressure Equipment 자체 내구성의 의미 (실제 제작된 Material 및 두께 기준) 로 보면 되며, 해당 Equipment 상부에서 허용가능한 최고 Pressure을 의미한다.
Design pressure와 동등 또는 그 이상이어야 한다.
