ASME B31.3 Pipe Thickness Calculator
Calculate minimum required pipe wall thickness per ASME B31.3 for process piping maintenance and inspection planning.
Pipe Schedule & Dimension
ASME B36.10M / B36.19M pipe OD, ID, wall t, unit mass W_m, and MTO total W_tot = W_m × L × n by NPS and schedule.
Flange Dimension & Weight
ASME B16.5 flange OD, T, PCD, bolting, and mated-pair weight W_pair for NPS ½–24. WN hub bore uses Sch 40/STD ID.
Fitting & Valve Face-to-Face
Look up ASME B16.10 flanged valve face-to-face dimensions by NPS and pressure class.
Butt-Weld Fitting Dimensions
ASME B16.9 butt-weld fitting center-to-end and end-to-end dimensions with matching pipe schedule OD, ID, and wall.
Gasket Dimension & Selection
ASME B16.20 spiral-wound (ID × SE_OD × OR_OD) and RTJ (Ring No. · P · w×h) dimension lookup by NPS and class.
Piping Thermal Expansion & Anchor Load
ASME B31.3 ΔL = αLΔT with guided-cantilever loop H/W and F_anchor for CS, steam pipe, CPVC, stainless, and Cr-Mo — field screening, not CAESAR II.
Pressure Drop & Friction Loss
Darcy–Weisbach ΔP with Haaland f, B36 ID, Crane L/D fittings, and ΔP/100 gradient. Hero includes L + Σ L_eq.
Flow Rate & Velocity
Pipe velocity v = Q/A vs API RP 14E vc = C/√ρ. CS/SS liquid caps and Safe / Warning / Erosion Risk screening.
Link-Seal & Penetration Sleeve Sizing
Link-Seal modular seal sizing calculator: annular clearance C, LS model (LS-300–LS-575), link count N, and sleeve / core-drill ID from pipe OD.
