Theoretical Flange Weight Calculator

Enter the specifications and material type for your flange to calculate its theoretical weight. The calculator works for round flanges as well as square and rectangular plate flanges, and automatically subtracts the bore and the bolt holes.

Results are theoretical estimates; actual weight varies by facing, hub and machining tolerances.
