Piping Toolset

Free browser-based calculators for piping engineers, covering ASME B31.3 process piping (wall thickness, allowable pressure, leak test, branch reinforcement, miter bends, displacement stress range), B31.1 power piping, ASME BPE hygienic design (dead-leg L/d, slope and drainability, spray deviceflow, CIP velocity), expansion loop sizing, thermal growth, pipeline integrity (B31G, MAOP, hydrotest), water hammer surge, and more - 40 calculators in all. Every calculator documents its governing equation with code paragraph citations, states its limitations explicitly, and publishes a worked example that is simultaneously a CI-gated test fixture: if the app and the published example ever disagreed, the build would fail. Calculations run entirely in the browser; inputs are never transmitted.
