EN 1092-1_TYPE 05-A WELD PLATE FLANGES

The EN 1092-1 Type 05-A Flange (commonly referred to as a Blind Flange or Blank Flange) is a solid disc engineered to seal off the end of a piping system, valve opening, or pressure vessel. Unlike standard pipe flanges that feature a center bore to allow fluid flow, the Type 05 flange is completely solid across its face.

The "A" designation indicates a Flat Face (FF) execution, where the entire sealing area sits flat without a raised lip. Installed by bolting directly to a mating flange with a full-face gasket, it provides a safe, removable closure for line termination, pressure testing, and system maintenance.

Key Features

• Solid Blanking Structure: Designed without a center bore to withstand full system line pressure and dead-end hydraulic force securely.
• Type A Flat Face (FF): Features a flat sealing face that ensures even bolt pressure across the gasket, making it ideal for mating with other flat-face equipment or low-to-medium pressure systems to prevent flange distortion.
• Easy System Maintenance & Inspection: Serves as an accessible end-cap or access port, allowing quick unbolting for line cleaning, inspection, or future system expansion.
• Standardized EN Dimensions: Precision-engineered to European standard EN 1092-1 specifications, ensuring exact pitch-circle diameters, bolt hole alignments, and plate thicknesses.
• Versatile Material Range: Commonly forged and machined from carbon steel (e.g., P250GH, C22.8, S235JR), stainless steel (e.g., 1.4301/304, 1.4404/316L), and low-alloy steels for specific corrosion or temperature conditions.

Key Applications

• Chemical & Processing Facilities: Safely isolating non-operational process branches, pumps, and inline equipment during routine maintenance or retrofitting.

• Pipeline Termination: Sealing the ends of active or future piping runs in industrial process plants.
• Pressure Vessel Access & Manways: Covering inspection ports, handholes, and cleaning openings on tanks, heat exchangers, and reactors.
• Hydrostatic Pressure Testing: Temporary installation to blank off sections of piping systems during pressure testing and leak inspection before commissioning.
• Water & Wastewater Treatment: Low- to medium-pressure water lines, municipal supply networks, and drainage manifolds utilizing flat-face iron or steel connections.
