Flange Dimension Determination Logic
The Flange Size Calculator uses industry-standard specifications (e.g., ASME B16.5, ASME B16.47) to determine key flange dimensions. While not a direct mathematical formula, the process involves selecting the appropriate values based on:
- NPS: Nominal Pipe Size
- Pressure Class: Pressure Rating (e.g., 150#, 300#)
- Flange Type: (e.g., Weld Neck, Slip-On)
Therefore, the output dimensions are derived as:
Flange Dimensions = f (NPS, Pressure Class, Flange Type)
The calculator presents typical values for standard configurations.
