Flange Dimensions and Specifications for DIN 2527 PN10 Standards

Understanding DIN 2527 PN10 Flange Dimensions

When it comes to industrial piping systems, flanges play a critical role in connecting various components. Among the many standards that govern flange specifications, the DIN (Deutsches Institut für Normung) standard is widely recognized, particularly in Europe. One of the noteworthy specifications under this standard is the DIN 2527 PN10 flange, which is commonly used in various applications for its reliability and performance.

What is DIN 2527?

The DIN 2527 standard pertains to a type of flange that is made from different materials and comes in a variety of dimensions. The designation PN10 indicates the nominal pressure rating of the flange, which is 10 bar (or approximately 145 psi). This rating implies that the flange can withstand a pressure of 10 bars at a temperature of up to 120 degrees Celsius for water and similar liquids.

Key Dimensions

The dimensions of DIN 2527 PN10 flanges are crucial for ensuring compatibility with piping systems. The standard dimensions for these flanges are specified for different nominal diameters (DN) and include the following critical measurements

- Outer Diameter (OD) This is the overall width of the flange, which varies based on the size of the flange. For instance, a DN 100 flange has an outer diameter of 220 mm. - Inner Diameter (ID) This measurement corresponds to the bore of the flange, which needs to align with the diameter of the pipe it connects. For a DN 100 flange, the inner diameter is typically 100 mm. - Thickness The thickness of the flange varies with size. For a DN 100 flange, the thickness is approximately 16 mm. - Bolt Hole Diameter For proper attachment, the bolt hole diameter is specified, allowing for secure fastening of flanges. This typically ranges around 17 mm for a DN 100. - Number of Bolt Holes The number of bolt holes can differ, but for many DN sizes, it commonly includes 4 to 8 holes, ensuring a firm connection.

The overall surface of the flange is usually machined to provide a flat face (FF) or raised face (RF) to facilitate a proper seal when tightening bolts.

Applications

DIN 2527 PN10 flanges are utilized across various industries including water supply, waste management, and HVAC systems. Their adaptability makes them suitable for both industrial and domestic applications. Whether it’s transporting potable water or facilitating industrial processes, these flanges ensure leak-proof connections, which is vital to maintaining system integrity and efficiency.

Material Considerations

Flanges under the DIN 2527 standard can be made from different materials, including carbon steel, stainless steel, and other alloys. The choice of material greatly influences the flange’s ability to withstand different operating conditions such as temperature, pressure, and exposure to corrosive substances. Stainless steel flanges are preferred in environments subjected to rust or corrosion due to their durability and longer lifespan.

Conclusion

Understanding the dimensions and specifications of DIN 2527 PN10 flanges is essential for engineers and designers involved in the construction and maintenance of piping systems. By adhering to these standards, professionals can ensure that their connections are secure and capable of handling the pressures and temperatures expected in operation. This not only enhances the reliability of the piping system but also minimizes potential failures and maintenance costs in the long run. Whether you are in the planning stages of a new installation or managing an existing system, considering the appropriate flange dimensions is paramount for successful implementation.
