Flanges are used to connect pipes, valves, or other equipment in a piping system. The dimensions of flanges can vary depending on the specific standard being followed. Here are some common flange standards and their corresponding pipe dimensions:

ANSI/ASME B16.5:

Flange Sizes: 1/2" to 24"

Pressure Ratings: Class 150, 300, 600, 900, 1500, 2500 lbs

Facing: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ)

ISO 7005 (EN/DIN):

Flange Sizes: DN 10 to DN 6000

Pressure Ratings: PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100, PN 160

JIS B2220:

Flange Sizes: 10A to 1500A

Pressure Ratings: 5K, 10K, 16K, 20K, 30K, 40K

Flanges have specific dimensions for outer diameter, inner diameter, bolt hole sizes, and thickness, which can vary based on the flange size and pressure rating. It is recommended to consult the relevant standard or specification document for precise and detailed dimensions specific to your requirements.
