The Robust, Pressure-Rated "Safety Shutter" for Piping Systems
Serving as the definitive closure for pipe ends or equipment nozzles, the primary function of the BS EN 1092-1 blank flange is to
withstand full system design pressure. Fabricated to specified thickness and material strength corresponding to its PN rating (e.g., PN16, PN25, PN40, PN63, PN100), it maintains structural integrity under maximum working pressure, including transient overpressure conditions, preventing deformation or leakage. Its solid disc structure acts as a dependable "safety shutter," ideal for
permanent or long-term isolation of pipe ends, unused branch connections, or as a
critical safety barrier during equipment maintenance to prevent accidental media ingress.
