Piping Toolset

49 free browser-based ASME piping calculators (B31.3, B31.1, BPE, B31G) where every published worked example is a CI-gated test fixture - if the app and the example disagree, the build fails. Paid tiers add relief sizing, flange/nozzle/hanger design, iso drawing, and FEA.

    Unlike generic plumbing calculators that focus solely on simple friction loss or pipe sizing, the platform handles high-stakes calculations like miter bends, branch reinforcements, water hammer surges, displacement stress ranges, and thermal growth. It translates code text into rapid, highly precise verification steps.

What is 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 device flow, 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.

Paid tiers add deliverable-focused tools:

  • Pro ($2.99/mo): Report Manager calculation-package builder, PiperSIF stress intensification factors (ASME B31J + HDPE), PiperPSV relief valve sizing (API 520 orifice sizing + B31.1 App II reaction forces), pipe-size and material-property autofill from licensed code tables.

  • Pro Plus ($7.99/mo): PiperHGR spring-hanger selection with 3D assemblies, PiperNOZ equipment nozzle load checks (API 610/560/660/661, NEMA SM 23), PiperFLG ASME Section VIII Appendix 2 flange design with B16.5-2025 pressure-temperature ratings.

  • Ultimate ($14.99/mo): PiperISO isometric drawing, PiperSTR AISC 360-22 pipe support structural design, PiperFEA screening-grade nozzle-to-shell FEA.

Pricing:

Freemium. Pro $2.99/mo ($29/yr) - Pro Plus $7.99/mo ($79/yr) - Ultimate $14.99/mo ($149/yr). Free calculators forever, no login.
