Product Selection Differences for Flange Fittings

When selecting Flange Fittings, there are several key differences to consider:

1. Material: Flange fittings can be made from various materials such as carbon steel, stainless steel, brass, and PVC. The material chosen should depend on the specific application, considering factors like corrosion resistance, pressure rating, and temperature requirements.

2. Pressure Rating: Flange fittings come in different pressure classes, such as 150, 300, 600, 900, 1500, and 2500. Ensure that the pressure rating of the flange fitting matches the pressure requirements of the system it will be used in.

3. Size and Dimensions: Flange fittings are available in different sizes and dimensions to accommodate various pipe diameters. It is essential to select the correct size to ensure a proper fit and prevent leakage.

4. Flange Face Type: Flange fittings can have different face types, such as flat face, raised face, and ring-type joint. The choice of flange face type depends on the application and the type of gasket being used.

5. Flange Facing Finish: The finish of the flange facing is crucial for ensuring a leak-tight connection. Common facing finishes include serrated, smooth, and spiral serrated finishes.

6. Gasket Material: The type of gasket material used with the flange fitting is essential for preventing leaks. Common gasket materials include rubber, graphite, and PTFE, each with its own advantages and suitability for different applications.

7. Operating Conditions: Consider the temperature, pressure, and fluid media that the flange fitting will be exposed to when selecting the appropriate type of flange fitting. Different materials and designs perform better under specific operating conditions.

By considering these key differences, you can choose the most suitable flange fitting for your specific application requirements.
