Product Selection Differences for ANSI Flanges

When selecting ANSI flanges, important factors to consider include:

1. Pressure Rating: ANSI flanges are rated according to pressure classes, such as 150, 300, 600, 900, 1500, and 2500. Ensure that the flange you select matches the pressure requirements of your system.

2. Size: ANSI flanges are available in various sizes, ranging from 1/2 inch to over 60 inches. Choose a size that matches the piping system it will be used in.

3. Facing Type: ANSI flanges come in different facing types, such as flat face (FF) or raised face (RF). The facing type affects the sealing capability of the flange.

4. Material: Select a material that is compatible with the fluid or gas being transported and suitable for the operating conditions (temperature, pressure, corrosion resistance).

5. Flange Type: ANSI flanges come in several types, including weld neck, slip-on, socket weld, threaded, and blind flanges. Choose the type that best suits the requirements of the piping system.

6. Standards: Ensure that the flanges meet ANSI/ASME standards for dimensional specifications and performance.

7. Cost: Consider the overall cost of the flange, including initial purchase price, maintenance requirements, and lifespan.

By carefully considering these factors, you can select the appropriate ANSI flange for your specific application.
