Built by an engineer,
for engineers
PipingCalcPro is an independent project that replaces spreadsheets and expensive desktop software with fast, ASME-compliant web tools that work anywhere.
Why this exists
Day-to-day piping engineering involves the same handful of calculations — wall thickness checks, support spacing, pressure drop — repeated constantly. The standard workflow is a pile of spreadsheets: easy to corrupt, hard to audit, impossible to share reliably.
Commercial tools like CAESAR II or AutoPIPE solve the heavy-stress analysis side, but they are expensive, Windows-only, and overkill for the quick checks engineers do every day.
PipingCalcPro fills the gap: a browser-based toolkit that runs the right formula, cites the right code clause, and shows you every substituted value so you can defend the result in a design review.
Available tools

Independent project
PipingCalcPro is maintained by a single developer. Calculations are provided for guidance and should be verified by a qualified engineer before use in any safety-critical application. If the tools save you time, consider supporting the project.
