Blind Flange Type 05/B1 EN1092-1 PN25
TECHNICAL DESCRIPTION
Blind flanges according to standard EN1092-1 / type 05 / B1 are pipeline elements with a wide size range, which are used as silencers in the construction of steel pipelines and pipe segments (spools).
We stock blind steel flanges according to EN1092-1 type 05 / with sealing surface B1, but we also have the necessary machining equipment, which allows us to offer flanges with sealing surfaces.
• sealing surface type A, B2, C, D, E, F
• non-standard sealing surfaces on request
• profile grooves for metal sealing rings (segments) type RTJ
• threaded type flanges
• flanges made to customer specifications, and others.
SUPPORTED MATERIALS IN STOCK:
• Carbon steel
P245GH (1.0352) / EN 10222-2
Dimensions:DN 10 – 600
The BLIND FLANGE TYPE 05/B1 EN1092-1 PN25 is a high-performance industrial sealing component designed for permanent or temporary closure of piping systems. Manufactured in compliance with the EN1092-1 standard, this flange ensures reliability and safety in high-pressure applications up to PN25. Its robust construction makes it ideal for use in oil and gas, chemical processing, water treatment, and other demanding sectors where leak-proof performance is critical.Key features include:Material: High-grade steel for durability and corrosion resistancePressure Rating: PN25 (25 bar), suitable for intense operational conditionsStandard: EN1092-1, guaranteeing compatibility and interoperabilityType 05/B1 design for easy installation and secure sealingApplications: Ideal for blanking off pipes, valves, or pressure vesselsThis blind flange is engineered to provide a tight seal, preventing fluid or gas leakage, and is tested rigorously to meet international quality standards. It is available in various sizes and can be customized to fit specific project requirements, ensuring optimal performance and longevity in industrial environments.
