Engineering Reference Tables & Data
Free, standards-backed reference data for piping and valve engineering — pipe dimensions and weights, friction coefficients, valve flow coefficients, and fitting losses. Each table cross-links the SimuPipe tools that use the same data.
Dimensions & Standards
Pipe Schedule Tables
OD, wall thickness, and ID for ASME/ASTM and EN/DIN schedules across 11 materials.
Steel Pipe Weight Chart
Carbon steel Schedule 40 weight per metre and per foot — empty and full of water.
Flange Dimensions (ASME & EN)
Raised-face tables for ASME B16.5 & B16.47 Class 150–2500 and EN 1092-1 PN 6–40, in inches or mm.
Bolt-Hole Orientation
ASME B16.5 flange bolt-hole orientation reference guide.
Coefficients & Properties
Pipe Roughness (ε)
Absolute roughness in mm and ft for Darcy-Weisbach / Colebrook-White friction.
Fluid Properties
Density, viscosity, vapor pressure, molar mass and γ for 38 liquids and gases.
Hazen-Williams C-Factor
Roughness coefficient C by material, new vs aged, with the head-loss equation.
Cv / Kv Conversion
Convert valve flow coefficients, with a conversion table and typical Cv values.
Fitting K-Factors (Crane TP-410)
Resistance coefficients for valves and fittings, with the minor-loss equation.
