반응형 INDUSTRIAL ENGINEERING/Pressure Vessels & Tanks4 방폭(Ex) 구역 설정 기준 – Zone 0·Zone 1·Zone 2 실무 적용 정리 산업 설비·플랜트·배관·가스라인에서 적용하는 방폭(Explosion Protection) 구역 설정 기준을 정리한다. 방폭 구역은 공정 중 발생할 수 있는 가연성 가스·증기·분진이 어느 정도 빈도로 존재하는지에 따라 Zone 0, Zone 1, Zone 2로 구분한다. 본 글은 현장에서 바로 사용 가능한 구역 설정 조건, 장비 설치 기준, 배관·밸브·센서 선택 기준을 중심으로 구성한다.방폭 구역이 필요한 이유플랜트, 반도체 케미칼, Petrochemical, 제약 API 생산, 가스 저장 및 이송 설비에서가연성 물질이 공기와 혼합될 경우, 특정 농도 범위(폭발 한계 LEL~UEL)에서 점화원이 존재하면 폭발 위험이 생긴다.따라서 설계 단계에서 폭발성 대기(Explosive Atmosphere) 발생 가능.. 2025. 11. 23. Pressure Relief Devices – Safety Valve vs Rupture Disc Explained 1. IntroductionAsk anyone who’s ever signed off a pressure vessel — you can design it perfect, weld it perfect, hydrotest it perfect.But if you mess up the relief setup? That’s a bomb sitting quietly in the corner.Pressure relief devices aren’t some paperwork requirement; they’re what keep plants from turning into accident reports.Two main players here: safety valves and rupture discs. Same goal.. 2025. 11. 3. Pressure Vessel Testing & Inspection – What Really Happens on Site Here’s the truth:You can have the best drawings, the cleanest welds, and still end up with a ticking bomb if your testing is sloppy.Pressure vessel testing isn’t paperwork. It’s the part where you find out if what’s on paper actually holds pressure.In the field, this is where the vessel proves it’s worth the plate thickness — and where bad welding, poor heat treatment, or cheap gaskets show thei.. 2025. 11. 2. What Is a Pressure Vessel? Field Notes on Design, Types, and Safety Codes IntroductionAsk anyone who’s spent a few years around plants —a pressure vessel isn’t just a big metal tank.It’s the heart of any process line. When one goes wrong, you’re not just stopping production; you’re flirting with disaster.These vessels hold everything from compressed nitrogen to solvent vapor, and they do it under serious pressure.That’s why design, welding, and inspection need to be d.. 2025. 11. 2. 이전 1 다음 반응형
