Diameter of bolt circle 4. Flange weight Pipe data: 1. Outside diameter 2. Wall thickness 3. Schedule 4. Weight 5. Weight with liquid Gasket data: 1. Gasket inside diameter 2. Gasket outside diameter 3. Spiral wound dimensions 4. Type R ring dimensions And many more fields. All values are calculated or sourced directly from official standards like ASME B16.5 "Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard". Looking up flange, pipe, and bolt data with Flange Bolt Chart is far faster and less error prone than searching through PDF charts and tables. The sole purpose of the tool is to make it as simple as possible for pipefitters, steamfitters, and others working in piping to look up piping information like flange bolt size and torque pattern.
