For ASME B16.5 Threaded Flanges, the dimensions can vary based on the nominal pipe size (NPS) and the pressure class. Here are approximate dimensions for Class 2500 Threaded Flanges in inches:
Ranges from 1/2 inch (DN 15) to 24 inches (DN 600) and larger.
The OD varies with NPS. For example, the OD of a 1/2-inch flange is approximately 10.75 inches, while the OD of a 24-inch flange is around 53.50 inches.
This dimension increases with the size of the flange. For instance, the BCD of a 1/2-inch flange is approximately 9.50 inches, while the BCD of a 24-inch flange is around 49.50 inches.
The number of bolt holes varies depending on NPS. Smaller sizes may have fewer bolt holes (e.g., 4), while larger sizes may have more (e.g., 20).
The diameter of the bolt holes varies with NPS. For example, the bolt hole diameter for a 1/2-inch flange is approximately 1.13 inches.
These dimensions are approximate and specific dimensions may vary based on the manufacturer and the standards being followed. For precise and detailed dimensions, it's recommended to refer to the ASME B16.5 standard or consult the manufacturer's specifications for the specific flange size and class.
