EN1092-01 Carbon Steel Plate Flanges:

1. Standard: EN 1092-1

EN 1092-1 is a European standard that specifies the requirements for flanges and their associated fittings. This standard covers various types of flanges, including those used in industrial piping systems, ensuring uniformity and compatibility across different applications.

2. Type 01

Type 01 refers to a plate flange design. This type of flange is characterized by its flat or raised face, which is used to connect pipes, valves, and other components in a piping system. Plate flanges are typically used in situations where a bolted connection is needed, and they are designed to accommodate a range of pressure and temperature conditions.

3. Material: Carbon Steel

Carbon Steel is the material used for the flange. Carbon steel is known for its strength, durability, and relatively low cost. It is suitable for various industrial applications, especially where the environment is not excessively corrosive or where higher strength and toughness are required.

4. PN 2.5

PN 2.5 stands for "Pressure Nominal 2.5 bar." This indicates the flange is rated for a maximum working pressure of 2.5 bar (approximately 250 kPa or 36 psi). This rating helps in determining the flange's suitability for specific pressure applications in a piping system.

5. Key Features and Applications:

Design: The flange is designed as a plate flange, which can have either a flat face or a raised face depending on the specific requirements of the application. The face design affects how it seals against the connected component.

Size and Dimensions: The exact dimensions (such as diameter, bolt hole spacing, and thickness) will vary according to the standard EN 1092-1 specifications. This ensures compatibility with other components designed to the same standard.

Pressure Rating: With a PN 2.5 rating, the flange is intended for applications involving relatively low pressures. This makes it suitable for systems where the pressure does not exceed 2.5 bar.

Applications: EN 1092-1 Type 01 carbon steel plate flanges are commonly used in various industrial and commercial piping systems. These might include water and wastewater treatment, HVAC systems, and other applications where low to moderate pressure is present.

Installation: The flange is bolted to other flanged components using bolts and gaskets to create a secure, leak-proof connection in the piping system. Proper installation and maintenance are crucial for ensuring the flange performs effectively under operating conditions.
