Pipe sizing, pressure drop, and material take-off tools.
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
Look up ASME B36.10M pipe outside diameter, inside diameter, wall thickness, and unit weight by NPS and schedule.
Flange Dimension & Weight
Look up ASME B16.5 weld neck RF flange dimensions, bolt circle, and approximate weight for Class 150, 300, and 600.
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
Look up ASME B16.20 spiral wound and RTJ ring gasket dimensions by NPS and pressure class.
Thermal Expansion & Loop Sizing
Calculate ASME B31.3 thermal growth and screen L-shape / U-loop leg length from material, T1/T2, and straight-run length.
Pressure Drop & Friction Loss
Darcy–Weisbach pressure drop with NPS/schedule ID, fittings as equivalent length, and ΔP in bar and psi.
Flow Rate & Velocity
Compute pipe velocity v = Q/A and flag API RP 14E erosion velocity limit vc = c / √ρ.
