Features of Class 2500 Blind Flanges
- Flange OD (Outer Diameter): The overall diameter of the flange.
- Bolt Circle Diameter (BCD): The diameter of the circle where the bolts are located.
- No. of Bolt Holes: The number of bolt holes in the flange.
- Bolt Hole Diameter: The diameter of each bolt hole.
- Flange Thickness (T): The thickness of the flange body.
Class 2500 Blind Flanges Pressure-Temperature Rating
- Class 1500 indicates the maximum pressure rating of the flange (1500 lbs at a reference temperature of 100°F). The pressure capacity decreases at higher temperatures, so consult the ASME B16.5 charts for pressure-temperature ratings.
ANSI / ASME B16.5 Class 2500 Blind Flange, due to its high-pressure tolerance, is commonly used in industries with stringent requirements.

Häufig gestellte Fragen
A 2500 Blind Flange is a high-pressure rated flange used to seal the end of a pipe, valve, or vessel. It is defined by its pressure rating of 2500 lbs and conforms to standards like ANSI / ASME B16.5. Unlike other flanges, a blind flange has no hole in the center, effectively blocking fluid flow in pipelines or system components.
The choice of gasket for Class 2500 Blind Flanges depends on the application’s pressure, temperature, and chemical resistance requirements. Common types of gaskets include:
- Ring Type Joint (RTJ) Gaskets for high-pressure applications.
- Spiral Wound Gaskets for high-temperature or high-pressure applications.
- Soft Gaskets (such as graphite or PTFE) for less aggressive environments.
Class 2500 flanges have a higher pressure rating than lower classes like Class 1500, Class 600, and Class 300. They are designed to withstand significantly higher pressures, making them suitable for use in extreme environments such as high-pressure pipelines, reactors, and critical industrial processes.
