Api 615 Fixed -If the manual valve is behind a fence, up a ladder, or inside a smoke-filled rack, you cannot meet that 10-minute window. That means you need automated isolation. Myth 1: "Our control valves can act as emergency isolation." Reality: No. Control valves are designed for throttling, not bubble-tight shutoff. API 615 requires dedicated EIVs with shutoff capabilities (Class V or VI shutoff). "We have fireproofing on the vessel, so the pipe is fine." Reality: Piping fails faster than vessels due to higher surface area-to-volume ratios. Pipe supports and thin-walled sections need specific fire protection per API 615. api 615 When we talk about process safety in refineries and chemical plants, the conversation usually starts and ends with pressure vessels, relief valves, and control systems. But what about the miles of pipe snaking through your facility? If the manual valve is behind a fence, As the industry moves toward Inherently Safer Design , the ability to mechanically stop a leak from the control room (or automatically via sensors) is no longer a luxury—it is a necessity.
