Dimensions and Specifications for DIN 2527 PN16 Flanges

Understanding DIN 2527 PN16 Flange Dimensions

Flanges are crucial components in piping systems, providing a reliable means to connect different pipe sections, valves, pumps, and other equipment. Among the various flange standards globally, the DIN (Deutsches Institut für Normung) standard is one of the most recognized and widely used, especially in Europe. This article will focus on the dimensions and characteristics of the DIN 2527 PN16 flange, a common choice in many industrial applications.

What is DIN 2527 PN16 Flange?

The DIN 2527 flange is a type of flat, raised face flange that conforms to the German standard specifications. The PN in its designation stands for Pressure Nominal, and the number 16 indicates that this type of flange is designed to handle a maximum allowable pressure of 16 bar at a certain temperature. This makes it suitable for various applications, including water supply lines, heating systems, and chemical processing.

Key Characteristics

1. Material DIN 2527 flanges can be manufactured from various materials, including carbon steel, stainless steel, and alloy materials. The selection of material often depends on the specific application, including factors such as fluid type, temperature, and environmental conditions.

2. Pressure Rating The PN16 designation implies that the flange can handle pressures up to 16 bar (approximately 232 psi). This makes it a versatile choice for many industrial settings.

3. Dimension Standards The dimensions of DIN 2527 flanges are strictly defined to ensure compatibility and secure connections. These flanges typically feature a flat surface and may have either a mirrored or non-mirrored finish, depending on the application requirements.

Dimensions of DIN 2527 PN16 Flange

The following table summarizes the dimensions typically associated with the DIN 2527 PN16 flange

| Nominal Diameter (DN) | Bolt Circle Diameter (D) | Number of Bolts (n) | Bolt Size (d) | Flange Thickness (t) | Weight (kg) | |-----------------------|--------------------------|---------------------|----------------|----------------------|-------------| | 10 | 70 | 4 | M10 | 5 | 0.8 | | 15 | 80 | 4 | M10 | 5 | 0.9 | | 20 | 90 | 4 | M10 | 5 | 1.1 | | 25 | 100 | 4 | M10 | 5 | 1.5 | | 32 | 110 | 4 | M10 | 5 | 2.0 | | 40 | 130 | 4 | M10 | 5 | 2.5 | | 50 | 150 | 4 | M10 | 5 | 3.5 | | 65 | 165 | 4 | M10 | 6 | 4.5 | | 80 | 185 | 8 | M12 | 7 | 7.0 | | 100 | 210 | 8 | M12 | 8 | 9.5 |

Note The dimensions above are indicative and can vary based on manufacturers or specific requirements.

Installation and Maintenance

When installing DIN 2527 PN16 flanges, it’s essential to ensure proper alignment and utilize correctly sized bolts for secure fastening. Proper sealing materials should be used to prevent leaks, especially in systems that handle fluids at high pressures. Regular inspections and maintenance are crucial to detect any signs of wear or damage, which can help avoid catastrophic failures or system downtime.

Conclusion

The DIN 2527 PN16 flange is a reliable and versatile choice for a wide range of applications across various industries. With its standardized dimensions and robust pressure rating, it plays a critical role in ensuring the integrity and functionality of piping systems. Understanding its specifications and proper maintenance practices can lead to enhanced safety and performance in any industrial environment. Whether you're designing a new system or upgrading existing infrastructure, the DIN 2527 PN16 flange is certainly worth considering.
