Blind Flange Type 05/B1 EN1092-1 PN100

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 – 350

Description

The BLIND FLANGE TYPE 05/B1, compliant with EN1092-1 PN100, is a high-pressure sealing solution designed for industrial piping systems requiring secure termination. Manufactured to exacting standards, this flange ensures leak-proof performance in demanding environments, including chemical processing, oil and gas, and power generation applications. Its robust construction and precise dimensions make it ideal for systems where safety and reliability are paramount.Key features include:Material Grade: Carbon steel or stainless steel options for corrosion resistancePressure Rating: PN100 (100 bar) for high-pressure applicationsFace Type: Raised face (Type 05) as per EN1092-1 specificationsGasket Compatibility: Designed for standard spiral wound or ring joint gasketsTemperature Range: Suitable for operations from -29°C to +400°CThis blind flange is engineered to provide a permanent or temporary seal on pipe ends, valves, or pressure vessel openings, preventing fluid flow and allowing for easy system maintenance. It is machined to ensure perfect flatness and bolt hole alignment, facilitating straightforward installation and reducing downtime. With its certification to EN1092-1, it meets European quality and safety standards, offering peace of mind for critical infrastructure projects.
