EN 1092-1 PLATE FLANGE DIMENSIONS & WEIGHTS

WHAT IS A “TYPE 01” EN1092-1 PLATE FLANGE?

A “Type 01” flange according to EN 1092-1 standard refers to a plate flange, also known as a flat flange or slip-on flange. The EN 1092-1 standard, which is widely used in European and global markets, specifies dimensions, tolerances, and material requirements for a wide range of flanges used in various piping systems. Type 01 plate flanges are one of the several flange types defined in this standard, designed for general use across multiple applications.

Key Characteristics of Type 01 EN 1092-1 Plate Flange

  • Design and Construction: Type 01 flanges are flat, circular discs with bolt holes around the perimeter for attaching to other flanges, pipes, or equipment. They have a relatively simple construction compared to other flange types, making them easier to manufacture and cost-effective.

  • Installation: These flanges are designed to slip over the end of the piping before welding. The flange is then welded both on the inside and outside to secure it in place, providing good strength and preventing leak paths.

  • Applications: Due to their straightforward design and ease of installation, Type 01 plate flanges are used in a wide variety of applications, from low to medium pressure and temperature environments. They are suitable for water, gas, and some chemical applications in industries like water treatment, heating and cooling systems, and general piping installations.

  • Materials: Type 01 flanges can be made from a variety of materials to match the piping system and application requirements, including carbon steel, stainless steel, and alloy materials. The choice of material is dictated by factors such as the fluid medium, operating temperature, and corrosion resistance requirements.

  • Pressure and Size Ratings: The EN 1092-1 standard provides specifications for Type 01 flanges across a range of pressure designations (PN) and nominal sizes (DN). This allows for their use in a diverse set of conditions and system sizes.

Advantages

  • Cost-Effectiveness: The simplicity of their design makes Type 01 plate flanges one of the more economical flange types, especially for applications where high-integrity sealing is not critical.
  • Versatility: They can be used in various installations due to their compatibility with different piping materials and suitability for a range of pressures and temperatures.
  • Ease of Installation: The slip-on design facilitates easier alignment and assembly in the field, reducing installation time and costs.

Type 01 plate flanges represent a basic yet versatile flange type within the EN 1092-1 standard, offering a practical solution for forming flanged connections in a variety of piping systems. Their selection depends on the specific requirements of the application, including the desired balance between performance, cost, and ease of installation.

WHAT MEANS “TYPE 01” ACC. TO EN 1092-1?

“Type 01” according to EN 1092-1 refers to plate (flat) flanges within the scope of the European standard EN 1092-1, which specifies the dimensions, types, and material requirements for steel flanges used in various piping systems. This classification system is part of a broader set of standards that provide comprehensive guidelines for flange manufacturing and application across Europe and globally.

Key Features of Type 01 Flanges

  • Design: Type 01 flanges are flat, circular discs with bolt holes around their perimeter. Their simple design facilitates easy alignment and assembly in piping systems.
  • Installation: These flanges are designed to slip over the pipe. They are typically welded on both the inside and outside to secure the connection and ensure a tight seal. This slip-on method simplifies the installation process, making it quicker and reducing costs compared to some other flange types.
  • Application: Type 01 flanges are versatile, and used across a wide range of applications from low to medium pressure and temperature settings. They are suitable for systems transporting water, air, and some chemicals, making them a popular choice in industries such as water treatment, heating and ventilation, and general manufacturing.

EN 1092-1 Standard

EN 1092-1 provides a harmonized standard for flanges within the European market, replacing various national standards to ensure consistency and compatibility across borders. It covers flanges in sizes up to DN 4000 and pressure designations from PN 2.5 to PN 400, offering a wide range of specifications for different applications and service conditions.

The “Type 01” designation within EN 1092-1 specifically identifies plate flanges, distinguishing them from other types of flanges covered by the standard, such as:

  • Type 02: Loose plate flanges with weld-on plate collar.
  • Type 11: Weld neck flanges.
  • Type 05: Blind flanges.

Each type serves different engineering and design needs, providing options for secure flange connections in a variety of operational contexts.

In summary, “Type 01” according to EN 1092-1 specifies plate flanges, recognized for their straightforward design, ease of installation, and versatility across various low to medium-pressure applications. This standardization ensures that flanges meet consistent quality and performance criteria, facilitating their use in international projects and applications.

TOLERANCE EN1092-1 PLATE FLANGES

EN 1092-1 outlines the specifications for various types of flanges, including plate flanges (Type 01). The standard provides detailed tolerances for dimensions critical to the manufacturing and functionality of these flanges. These tolerances ensure that the flanges can be interchangeably used in piping systems while maintaining a reliable seal and proper fit with mating components.

Here are some key dimensional tolerances typically specified:

Outside Diameter (D):

This tolerance ensures that the flange fits correctly with other mating flanges and components.

Thickness (e):

The tolerance of the thickness of the flange is crucial for ensuring that the flange can withstand the designated pressure without failing.

Diameter of Bolt Circle (P):

Accurate bolt circle diameter is essential for aligning bolt holes of mating flanges, ensuring bolts can be inserted without misalignment issues.

Diameter of Bolt Holes (d2):

The tolerance here allows a little extra space to accommodate bolts, taking into account any slight misalignments and making assembly easier.

Flange Face Surface Finish:

Though not a dimensional tolerance per se, the surface finish of the flange face where the gasket will sit is crucial for ensuring a proper seal. EN 1092-1 specifies requirements for the roughness of these surfaces, which is important for the sealing capability.

Bore Diameter (D1):

For plate flanges that are directly connected to the pipe, the bore diameter tolerance ensures a proper fit over the pipe without excessive space or interference, facilitating a smooth flow.

Tolerances for these dimensions are carefully defined to ensure that flanges manufactured by different producers are compatible with each other and can perform effectively in a variety of applications. These tolerances also account for manufacturing processes’ inherent variability, ensuring that despite these variations, the flanges can still function as intended.

Given the importance of adhering to these tolerances for the safety and functionality of piping systems, manufacturers and engineers should always refer to the latest version of the EN 1092-1 standard for the most accurate and applicable tolerance values.
