Dimensions and weights (in kgs.) of EN 1092-1 Type 13 threaded flanges for European piping systems
EN 1092-1 THREADED FLANGE DIMENSIONS & WEIGHTS
WHAT IS A “TYPE 13” EN1092-1 WELD NECK FLANGE?
A “Type 13” flange according to EN 1092-1 refers to a hubbed threaded flange. This specification comes under the broader EN 1092-1 standard, which outlines dimensions, tolerances, and material requirements for a wide array of flanges used in various piping systems across different industries. While “Type 11” is the designation for standard weld neck flanges within the EN 1092-1 standard, “Type 13” specifies a variant that combines the characteristics of a weld neck flange with the convenience of a threaded connection.
Key Characteristics of Type 13 EN 1092-1 THD Flanges
Threaded Connection: Unlike the standard weld neck flange (Type 11) that requires welding to connect to a pipe, Type 13 flanges feature internal threads. This allows them to be screwed directly onto a corresponding externally threaded pipe, facilitating easier installation and removal without the need for welding.
Hubbed Design: The flange includes a hub, which increases its strength and rigidity. This design feature also helps to distribute stress more evenly across the flange and the connected pipe, enhancing the overall integrity of the connection.
Applications: Type 13 flanges are suitable for applications where welding is not feasible or where quick assembly and disassembly are required for maintenance or system modification. They are commonly used in low to moderate-pressure and temperature environments.
Material Specifications: As with other flanges specified in EN 1092-1, Type 13 flanges can be made from various materials, including carbon steel, stainless steel, and alloy materials, to suit different operational requirements and media compatibility.
Pressure and Size Ratings: The EN 1092-1 standard provides dimensions and pressure ratings for Type 13 flanges, ensuring they can be appropriately selected to match the needs of specific applications and comply with the required safety and performance standards.
Advantages
Ease of Installation and Removal: The threaded connection allows for easier installation and removal compared to welded connections, reducing labor and downtime.
No Welding Required: Eliminates the need for welding equipment and expertise, making it a convenient option for various settings, including those where welding may pose safety risks.
Versatile Applications: Can be used in various settings where the fluid handled and system conditions are compatible with a threaded connection.
Considerations
Sealing Integrity: While providing a solid connection, the sealing integrity of threaded flanges under extreme conditions may not match that of welded connections, limiting their use in high-pressure or high-temperature applications.
Thread Compatibility: It’s crucial to ensure compatibility between the flange threads and pipe threads to avoid cross-threading or misalignment.
In summary, a “Type 13” EN 1092-1 “hubbed” threaded flange offers a unique combination of ease of installation and the mechanical strength provided by its “hubbed” design, making it suitable for specific applications where welding is not desired or practical.
WHAT MEANS “TYPE 13” ACC. TO EN 1092-1?
“Type 13” according to EN 1092-1 designates a hubbed threaded flange. This specification is part of the EN 1092-1 standard, which details requirements for steel flanges used in various piping systems, including dimensions, materials, and pressure ratings. Type 13 flanges incorporate both the structural support feature of a hub and the convenience of a threaded connection.

THREADING SPECIFICATIONS FOR EN1092-1 TYPE 13 FLANGES
EN 1092-1 flanges, specifically those requiring threading like the Type 13 hubbed threaded flanges, typically follow the ISO 7-1 standard for threading.
This standard specifies the requirements for ISO metric screw threads with the designation “Rp” for internal threads. ISO 7-1 is widely used for pipe threads where pressure-tight joints are made on the threads themselves. The threading is designed to ensure compatibility and a secure fit between interconnected piping components.
ISO 7-1 Threading Specifications
- Type: Taper external threads and parallel internal threads. The standard specifies dimensions, tolerances, and designation for both types of threads.
- Sealing Mechanism: The threads themselves can form a pressure-tight joint, not necessarily requiring additional sealing methods (e.g., gaskets) when properly engaged. However, in practice, some form of thread sealant (like PTFE tape or thread sealing compound) is often used to ensure a leak-proof connection.
- Compatibility: Designed for general use in joining and sealing pipes and fittings. The standardized dimensions facilitate the interchangeability of components across different manufacturers and systems.
For EN 1092-1 Type 13 flanges, the threading allows for direct screwing onto corresponding externally threaded pipe ends, making installation and removal straightforward without the need for welding. This type of connection is particularly advantageous for applications where frequent disassembly might be required or where welding is not feasible.
When specifying or working with EN 1092-1 Type 13 flanges (or any threaded piping components conforming to European standards), it’s essential to ensure that the threading conforms to ISO 7-1 to guarantee compatibility and a secure, pressure-tight connection.
