EN 1092-1 BLIND FLANGE DIMENSIONS & WEIGHTS
WHAT IS A “TYPE 05” EN1092-1 BLIND FLANGE?
A “Type 05” flange according to EN 1092-1 refers to a blind flange. The EN 1092-1 standard, which is prevalent in European and international piping systems, specifies the dimensions, tolerances, and material requirements for a wide variety of flanges, including blind flanges. Type 05 categorizes blind flanges within this standard, defining their unique characteristics and applications.
Key Characteristics of Type 05 EN 1092-1 Blind Flange
Design: Type 05 blind flanges are solid discs used to terminate the end of a piping system or to close off a pipe. Unlike other flange types, blind flanges do not have a bore, making them ideal for providing a secure seal at the end of a pipeline or for isolation purposes.
Applications: Blind flanges are used in various applications where it is necessary to temporarily or permanently seal off a section of a pipeline. This could be for testing, maintenance, or in case a pipeline needs to be expanded or modified in the future. They are essential components in both low and high-pressure systems and can be found in industries ranging from oil and gas to chemical processing and water treatment.
Installation: The installation of a Type 05 blind flange is straightforward, involving bolting the flange to a matching flange at the end of a pipe, with a gasket placed between the flanges to ensure a tight seal. This allows for easy access to the pipeline for inspection, cleaning, or modification.
Materials: As with other flanges defined by EN 1092-1, Type 05 blind flanges can be made from various materials, including carbon steel, stainless steel, alloy steel, and more. The material selection depends on the specific requirements of the application, such as the type of fluid being transported, operating temperature, and pressure.
Pressure and Size Ratings: EN 1092-1 provides specifications for Type 05 blind flanges across a range of pressure designations (PN) and nominal sizes (DN), accommodating a wide array of conditions and system sizes.
Advantages
- Versatility: Type 05 blind flanges can be used in a variety of settings and applications, offering flexibility for system design and modifications.
- Sealing Capability: When properly installed, blind flanges provide an effective and reliable seal, preventing leaks and ensuring the safety and integrity of the piping system.
- Ease of Installation: The simplicity of their design allows for easy installation and removal, facilitating access to the piping system when needed.
In summary, Type 05 according to EN 1092-1 specifies blind flanges, which are essential for sealing the ends of pipelines or isolating sections of a piping system. They offer a practical solution for a variety of applications, ensuring system integrity and providing operational flexibility.

TOLERANCE EN1092-1 BLIND FLANGES
The EN 1092-1 standard provides comprehensive details on dimensions and tolerances for various flange types, including Type 05 blind flanges. These tolerances are essential for ensuring that flanges fit properly within a piping system and maintain their integrity under operational conditions. However, due to the breadth of the standard, which covers flanges from DN 10 to DN 4000 across various pressure classes (PN 2.5 to PN 400), it’s challenging to list all specific tolerance values succinctly here.
For detailed and specific tolerance values, you should refer directly to the EN 1092-1 standard. Typically, the standard specifies tolerances for dimensions such as:
Outside Diameter (D): Ensures that the flange can properly align and fit within the system. The tolerance varies with flange size and can affect how the flange interfaces with other components.
Thickness (E): Critical for ensuring that the flange has the necessary strength to handle the designated pressure. Thickness tolerance can influence the flange’s ability to withstand operational stresses without failing.
Bolt Circle Diameter (K): The precision of this measurement is crucial for the alignment of bolt holes on mating flanges, facilitating the assembly process and ensuring the integrity of the bolted connection.
Diameter of Bolt Holes (D2): Typically, bolt holes are slightly oversized to allow for ease of alignment and bolting. The exact oversize amount is specified to ensure compatibility while accommodating manufacturing variances.
Flange Face Surface Finish: Specifies the roughness of the sealing surface to ensure compatibility with gasket materials and a proper seal. While not a dimensional tolerance, the finish quality is critical for the flange’s sealing function.
Given the variety of sizes and pressure classes covered by EN 1092-1, tolerance values for specific dimensions will vary. These values are meticulously outlined in tables within the standard, providing engineers and manufacturers with the necessary data to design and fabricate flanges that meet the required specifications for fit, function, and safety.
For precise tolerance information, accessing the EN 1092-1 standard through official sources or standards organizations is recommended. This direct reference will ensure that the most accurate and applicable data is used for engineering, design, and quality control purposes in flange manufacturing and application.
