ASME B16.5 Flanges
Pressure–temperature rating evaluator and flange dimension lookup (ASME B16.5-2025). Ratings interpolate linearly between table temperatures.
Result
Working pressure by class at this temperature
| Flange class | Allowable (psi) | vs. design |
|---|
Ratings are gauge pressures. Group ratings cover the listed material specs; always confirm the material's own temperature limits and applicable code (e.g. ASME B31.3) for the final design.
Dimensions (mm)
ASME B16.5-2025, SI units. O = flange outside diameter, tf = minimum flange thickness, bolt circle = drilling diameter, raised face = RF outside diameter. Bolt count/size and flange weights are not published in these tables.

Area Moment of Inertia — Sections
Cross-section properties for a rectangle, I-section and T-section: area, neutral axis, moment of inertia, section modulus and radius of gyration. Units follow the Imperial/Metric switch.
Result
Static Head & Pressure
Convert a fluid column height to hydrostatic pressure (or the reverse) using density or specific gravity. Results are shown in every pressure unit.
Result
Cylindrical Shell — ASME VIII-1
Internal-pressure design of a cylindrical shell per ASME BPVC Section VIII Div 1, UG-27(c), with Appendix 1-2 applied automatically when the pressure exceeds the thin-wall limits.
