WHAT IT DOES Computes flange bolt torque per the ASME PCC-1 4-pass tightening sequence, with bolt load, bolt stress, and the gasket factor / seating stress that drives the calculation. Pulls flange dimensions from ASME B16.5, tensile stress area from ASME B1.1, and bolt-material proof strength from A193 / A320. INPUTS - Flange size: 1" to 24" - Pressure class: 150, 300, 600, 900, 1500 - Gasket type: Spiral Wound, Ring Joint, Flat Non-Asbestos - Bolt material: B7, B7M, L7, B8 Cl.2 (per A193 / A320) - Lubricant: Dry, Moly, Anti-Seize, PTFE - Target bolt stress: 20-80% of yield (slider) RETURNS - Torque per bolt in ft-lbs and N·m - Bolt load per bolt and total assembly load (lb) - Bolt stress at the selected yield percentage (psi) - Effective nut factor K - ASME PCC-1 4-pass tightening sequence: 30%, 60%, 100%, plus a circular check pass STANDARDS REFERENCED - ASME PCC-1 - gasket factor, seating stress, tightening pattern - ASME B16.5 - flange dimensions and bolt count - ASME B1.1 - tensile stress area - A193 / A320 - B7, B7M, L7, B8 Cl.2 bolt material specs WHY THIS APP, NOT THE FREE ONES - Math is shown - formula and substitution visible for every result.
