Product Selection Differences for Blank Flanges

When selecting blank flanges, there are several key differences to consider, including:

1. Material: Blank flanges are commonly available in materials such as carbon steel, stainless steel, and alloy steel. The choice of material depends on factors like pressure, temperature, and corrosion resistance requirements.

2. Pressure Class: Blank flanges are available in various pressure classes ranging from 150 to 2500. The pressure class should be selected based on the operating pressure of the system.

3. Size: Blank flanges come in different sizes ranging from 1/2 inch to several feet in diameter. The size of the flange should match the pipe size it is being connected to.

4. Facing: Flange facing options include raised face, flat face, and ring-type joint facing. The facing type should be compatible with the gasket being used to ensure a proper seal.

5. Standards: Consider whether the flanges meet industry standards such as ANSI, ASME, or API standards to ensure compatibility with other pipeline components.

6. Corrosion Resistance: Depending on the application, it's essential to choose a blank flange with appropriate corrosion resistance properties, especially if the system will be exposed to corrosive environments.

7. Temperature Range: Ensure that the blank flange selected can withstand the temperature range of the system to prevent deformation or failure.

8. Price and Availability: Compare prices from different suppliers and consider the availability of the blank flanges to meet project timelines.

By carefully considering these factors, you can select the most suitable blank flange for your specific application.
