Plate Flange Weight Calculator
Calculate the theoretical weight of flat-face plate flanges. Choose DN, PN and material to see dimensions, bolt-hole details and a rotatable 3D model.

Flat face · automatic reference dimensions
Type 01 / A — flat face. This plate flange has no hub and no raised face. The bore and bolt holes are deducted from the calculated weight.

Dimensions and bolt pattern follow your selection.
Drag freely in any direction. Use arrow keys when the model is focused. Scroll to zoom out or back to the fitted view. The entire flange stays in view during rotation.

Plate Flange Weight Formula
W = π / 4 × (D² − B₁² − n × L²) × C₁ × ρ / 10⁹
D = flange outside diameter; B₁ = bore; L = bolt-hole diameter; n = number of holes; C₁ = plate thickness in mm; ρ = density in kg/m³. Quantity multiplies the unit weight.
Nominal geometry only. Edge breaks, tolerances, welds, coatings, bolts and packaging are excluded. Use the actual material density and approved drawing for a final weight check.
Standard & Calculation Scope
EN 1092-1:2018, Tables 11–15: PN 6, 10, 16, 25 and 40; DN 10–600. PN 40 is limited to DN 400: C₁ for DN 450–600 is purchaser-specified in Table 15 and is not auto-filled. Only Type 01 / A flat-face geometry is included. PN is a designation, not a pressure-temperature rating for every material.
Plate Flange Calculator FAQs
Is this the same as a slip-on flange?
This calculator covers a hubless Type 01 plate flange. A hubbed slip-on flange has additional material and requires a different geometry and weight calculation.
Can I use this weight for shipping?
This is a theoretical piece weight. Confirm actual finished weights and add packaging before arranging shipment.
Does this include a raised face?
No. This version calculates Type A flat-face flanges. A raised face changes the geometry and requires its own dimensions.
What should I include in my enquiry?
Send DN, PN, Type 01 / A, material grade, quantity, required standard edition, inspection requirements and delivery destination.
