Understanding EN1092 PN16 Flanges

The EN1092 PN16 flange follows the European standard norms, which ensure quality and consistency across various dimensions and forms. The designation "PN16" indicates that these flanges can withstand a nominal pressure of 16 bar (approximately 232 psi). This makes them suitable for many applications, effectively sealing piping connections to prevent leakage and loss of pressure.

Moreover, EN1092 PN16 flanges are typically made from materials ranging from carbon steel to stainless steel, depending on the specific requirements of the application. The material choice affects the flange's resistance to corrosion, temperature variation, and mechanical stress, illustrating the importance of selecting the correct type for your needs.

Key Specifications of EN1092 PN16 Flanges

When considering EN1092 PN16 flanges, a few crucial specifications should be understood:

  1. Dimensions: EN1092 flanges come in various sizes, with corresponding pipe sizes ranging from small-diameter pipes for residential use to large-diameter pipes used in industrial settings. Common sizes include DN10 to DN1200, providing versatility for different applications.

  2. Pressure Rating: As indicated, the PN16 rating signifies the maximum pressure these flanges can handle. This makes them ideal for water and gas transport systems, where pressure resilience is key.

  3. Material Grades: The flanges can be manufactured from different grades of materials, such as S235JR, S355, and stainless steel variants like 304 or 316, providing options for varying environmental conditions.

  4. Bolt Holes and Finish: EN1092 PN16 flanges usually feature smooth surfaces and standard bolt hole patterns, making installation straightforward. The number of bolt holes and their placement are designed to ensure an even distribution of pressure across the flange, which is critical for maintaining seal integrity.
