EN 1092-1_TYPE 05-A BLIND FLANGE

The EN 1092-1 Type 05-A Blind Flange is a heavy-duty, solid disc component specifically designed to seal off the ends of piping systems, valves, or pressure vessel nozzles. Unlike standard flanges that feature a central bore for fluid passage, the Type 05 flange is completely solid across its face to contain system pressure and isolate sections of a pipeline.

The designation "A" specifies a Flat Face (FF) execution, meaning the entire contact surface is flat without a raised lip. This design provides an even sealing surface that pairs with full-face gaskets, making it ideal for lower-pressure ratings or mating with flat-faced cast iron and steel equipment.

Key Features

• Solid Blanking Construction: Manufactured without a center bore to withstand full line pressure and securely terminate active or dormant pipeline runs.
• Type A Flat Face (FF): Provides an even distribution of bolt loading across the entire gasket area, minimizing flange distortion when mating with flat-face equipment.
• Easy Maintenance Access: Serves as a removable end cap that allows technicians to easily unbolt the flange for system inspections, internal cleaning, or future pipeline extensions.
• Standardized European Compliance: Precision-machined to strict EN 1092-1 dimensional tolerances, guaranteeing bolt hole alignment, pitch circle diameters, and overall plate thickness.
• Broad Material Adaptability: Readily produced from various carbon steels (e.g., P250GH, C22.8), stainless steels (e.g., 304L, 316L), and alloy steels to suit diverse thermal and corrosive operating environments.

Key Applications

• Chemical & Petrochemical Facilities: Isolating non-operational process branches, pumps, or inline equipment during maintenance cycles.
• Pipeline Termination: Sealing off dead ends or future expansion points in industrial process piping.
• Pressure Vessels & Tanks: Blanking inspection ports, manways, and cleaning nozzles on boilers, storage tanks, and heat exchangers.
• Hydrostatic Pressure Testing: Providing temporary, secure closure for piping segments during mandatory factory or field pressure tests.
• Water & Wastewater Infrastructure: Municipal water distribution lines, sewage treatment plants, and drainage systems utilizing flat-face flange connections.
