About Piping Toolset
Piping Toolset is a browser-based suite of ASME B31 / BPE calculators built and maintained by a practicing, licensed piping engineer — and every calculator is verified by the same fixture gate that blocks a release when a number goes wrong.
Who builds this
Matthew Norris, P.E. — Founder — Licensed Professional Engineer (Mechanical / Piping), with active P.E. licensure in Arizona, California, Kansas, Missouri, and Texas. Matthew has spent his career in mechanical and piping engineering across process, power, and hygienic work: pipe stress, pipe supports, pressure equipment, and the calculation reports that get them past review. Piping Toolset packages the checks he actually runs into tools any engineer can audit — connect on LinkedIn.
The product is operated by Flexible Piping Solutions LLC. Contact: support@pipingtoolset.com.
Why you can check the numbers
Credentials are a starting point, not the argument. Every calculator on this site publishes its governing equation with code-paragraph citations, states its limitations, and walks a fixture-verified worked example — and those fixtures re-run on every commit, so the published example and the live app cannot disagree without the build going red.
- Validation methodology — how every calculator is verified.
- Fixture coverage — every module and locked case, regenerated each build.
- Calculation changelog — the versioned record of calculation behavior.
- Source & citation policy — where every number comes from.
