Piping Toolset Reviews and Details

Questions & Answers

1. What makes Piping Toolset unique?

   Every calculator ships with a worked example, and that worked example is simultaneously a test fixture in the release gate. The numbers published on the page are the exact numbers CI checks on every commit — if the app and the published example ever disagreed, the build fails and nothing deploys.

   That closes a gap common in this space: tools that return a number without showing the method, and reference pages that explain a method without providing a tool. Piping Toolset puts the governing equation, its code paragraph citation, the stated limitations, a hand-checkable worked example, and the live calculator on a single page.

   Calculations run entirely in the browser. Inputs are never transmitted, which matters when the numbers belong to a client project.

2. How would you describe the primary audience of Piping Toolset?

   Practicing piping and stress engineers in process, power and EPC work — the people doing ASME B31.3 and B31.1 pressure design, branch reinforcement, SIFs and displacement stress range checks.

   A second, distinct audience on the ASME BPE side: process, validation and GMP engineers in pharmaceutical and biotech facilities, working dead-leg L/d, slope and drainability, spray-device coverage and CIP velocity.

   Also pipeline integrity engineers using B31G remaining-strength assessment, and instructors in piping-design programs who need worked examples with the method shown.

3. What's the story behind Piping Toolset?

   I am a licensed piping engineer, and I kept rebuilding the same calculations — wall thickness, branch reinforcement, expansion loops — in spreadsheets that were never quite trustworthy and never quite portable. The tools I could find online gave a number with no visible method, or explained the method without giving me anything to compute with. Neither is useful when you have to defend the result.

   So I wrote the calculators I wanted, then made a rule: I would not publish a calculator I could not prove. Every worked example on the site is a locked test case with a tolerance, re-run on every commit. A red fixture blocks the release. That constraint drove the whole design — the calculations are pure functions with no hidden state, which is what makes them verifiable in the first place.

   The free tier is deliberately generous because the calculations themselves should not be behind a paywall.

4. Why should a person choose Piping Toolset over its competitors?

   Auditability. An engineer stamping a drawing has to defend the number, so every calculator states its governing equation with the ASME paragraph cited, declares explicitly what it does not cover, and shows a worked example you can reproduce by hand.

   Three things back that up publicly: a fixture-coverage table generated from the live test suite at every build, so it cannot go stale; a versioned calculation changelog recording every change to calculation behaviour; and a source-and-citation policy stating where each value comes from. Code paragraph numbers are cited — ASME table values are never embedded, and remain user-supplied inputs.

   It is built and maintained by a licensed professional engineer who uses these calculations in practice.

5. Which are the primary technologies used for building Piping Toolset?

   TypeScript throughout, in an npm-workspace monorepo. The calculation engine is a standalone pure-function package with fixture-based verification under Vitest; the UI is React and Vite. Static landing pages are generated at build time by a dependency-free Node script that reads the same fixtures the tests use, so published examples cannot drift from verified behaviour.

   Hosting and serverless functions on Netlify. Supabase for magic-link auth and entitlement lookups, Stripe hosted checkout for subscriptions. Playwright for end-to-end tests gating deployment.

   The nozzle/shell FEA service is Python and FastAPI, running the open-source CalculiX solver.
