Your UT Bible, built for the field. Skip distance, D1.1 acceptance, beam path diagrams, encoder calibration, pipe data, and code criteria — offline, right in your pocket. Built by a working NDT tech for working NDT techs. No account. No internet. No subscription. Runs entirely on-device. CALCULATOR • Skip distance, half skip, and full skip for any angle and thickness • Beam spread — near-field distance, half-angle, and full spread • AWS D1.1 indication rating • Fracture mechanics — critical flaw size & ASME VIII Div 2/3 evaluation • Transfer correction (dB) • Encoder step resolution converter — steps/mm ↔ steps/in, with target-distance conversion for OmniScan calibration • Imperial and metric — switch units anytime BEAM PATH DIAGRAM • Interactive cross-section of your beam path through the material • Drag the probe to see coverage and position change in real time • Rotate to landscape for a fullscreen diagram WELD OVERLAY • Overlay Single V or Double V weld joint profiles on the beam path diagram • 5 standard weld presets, or enter custom bevel angle, root opening, and root face • Index offset — see where your probe index point sits relative to the weld centerline PIPE DATA • NPS 1/8" through 48" per ASME B36.10M • OD, ID, wall thickness, and scan length for every standard schedule • Stainless steel schedules where wall thickness differs from carbon steel (dual ASME standard support) • Apple Watch companion — quick pipe lookups on your wrist CODE ACCEPT/REJECT CRITERIA • ASME Section V, Article 4 • ASME B31.3 — Process Piping • AWS D1.1 — Structural Welding • API 1104 — Pipeline Welding • Inches and millimeters, side by side SETUPS & HISTORY • Build and save complete job setups — material, angle, frequency, weld geometry, and notes • Save calculation results with names and notes, then recall them in one tap for your records • Custom presets for your most-used configurations FREE & PRO • Free to download — skip distance, Snell's law, and a hands-on trial of every Pro tool • The full pipe chart is free for your first 10 lookups, then part of Pro • UTCal Pro unlocks unlimited use of everything: the full pipe chart, saved calculation history, custom presets & weld builder, encoder calculator, fracture mechanics, beam path diagrams, weld overlay, the full code library, and the Apple Watch app • One-time purchase — no subscription, ever WHY UTCAL • Built by a UT tech who got tired of doing skip math on a paper napkin • Works on the roof, in the ditch, in the shop — no signal required • Updated for the latest ASME, AWS, and API editions Questions or feature requests: support.utcal@carboncode.app
