About

ElbowData

This utility app helps industrial piping professionals quickly visualize pipe and elbow dimensions based on ISO/ASME standards. It offers instant calculations for diameter, angle, and radius, with support for various elbow formats and segmented elbows.

Highlights
  • Pipe and elbow dimension visualization
  • ISO/ASME standard compliance
  • Diameter, angle, radius calculation
  • 2D/3D/5D elbow formats
  • Segmented elbow generation
  • PDF abacuses and isometric sheets
  • Inch/millimeter conversion

With version 10, the application allows you to quickly visualize relational values related to pipes and elbows (Carbon Steel / Stainless Steel) according to ISO / ASME standards, making it a practical tool for industrial piping. An ultra-fast and intuitive way to retrieve: Diameter → Angle → Radius → Extrados → Intrados, regardless of the angle or diameter, in a single step. This provides up to 810 possible entries with one click. With this version, you can choose how to control diameter selection: via a slider, or via pre-filled input fields. ElbowData is free forever. Features Elbow formats: 2D / 3D / 5D Segmented elbows (lobster back): 8 generators / 12 generators / 16 generators PDF abacuses and isometric sheets including: bill of materials based on the selected language, technical memo, generator templates Inch / millimeter conversion Scientific calculator optimized for industrial piping Saved language selection This version benefits from UI, design, and ergonomic optimizations. Advertisements are now non-intrusive, ensuring a smooth and free user experience, with rewarded ads and technical articles related to industrial piping. You can support the developer with your suggestions and/or access the premium version. Thank you! If you have any feedback about the application, feel free to contact me by email.

Pipefitting, welding and fabrication calculator. Works fully offline. WeldUp Pocket gathers what a pipefitter, a welder and a fabricator have always worked out in their head or on a scrap of cardboard: the offset, the flat pattern, the saddle, the machine settings. Fifty tools, one entry, one answer. Nothing to look up, nothing to wait for. EVERYTHING WORKS OFFLINE Under a vessel, in a trench, up in the steel: the app never asks for a signal. No account, no ads, no data leaving the phone. PIPEFITTER • Offsets — one menu for every shape: offset, rolling offset (3D), single elbow, cut elbows • Tube bending — where to mark, how much to cut, what the wall takes • Pipe branch template, elbow branch template, swept tee — the saddle wrap, printed at full scale • Iso sketch — draw the run first, dimension it after, get the pipe takeoff and the spool pieces, and export the drawing as a PDF • My ISO plans — save a drawing under a name, reopen it and keep editing • Pipe bank & flag — several lines on one route, the cut list line by line • Custom elbow — the take-out of an elbow cut to an angle the catalog does not carry • Custom reducer — where to cut a stock reducer for the size you are missing • Accessory library — a valve's face-to-face measured once, dropped onto the drawing in one tap • Hydrostatic test, test records — test pressure, the gauge to use, a log of tests with photos • Line weight — pipe, water, insulation • Level — slope and plumb, two full-screen vials, zeroed on the spot WELDER • Amperage settings — process, material, thickness, joint and position: a 10 A window to dial into the machine • Weld shrinkage — shrinkage, angular pull, the gap to build in before you weld instead of fighting it after • Gas selection — mix, ISO 14175 class, cylinder color • Flow and purge — flow rate, time, chamber volume • Weld spacing — intermittent welds laid out ahead • Weld traceability — a record for every weld, filed by job • Metallurgical compatibility and weld defect diagnostics • Torch components — TIG and MIG diagrams, tap any part FABRICATOR • Bend, cone, shell course and hopper development — the profile drawn bend by bend, the drawing as a PDF • Frame drawing, cutting optimisation — sketched with a finger, miter angles, bars and sheets with the least waste • Bump bending, element lines, trigonometry — press, layout, squaring • Neutral axis, joint allowances, weight, check circumference • Drilling and tapping — speed, feed, pilot hole, and the drill to pick for any M size REFERENCES • Material specification — which diameter, which wall, which grade for which job, with the loads to put a number on it • Material traceability — the camera reads the pipe marking (grade, heat number, lot) and files it under the open job • Flange gasket — start from the fluid, not the gasket: first choice, fallbacks, the traps that cost • Flange bolting — how many bolts, what diameter, what length, what wrench: EN 1092-1 and ASME B16.5 • Section weight — square tube, angle, flat, round • Grades, weld and piping symbols, polarity, fitting dimensions, unit converter BUILT AROUND THE JOB Open a job: everything calculated after that hangs off it. History reopens each tool with its values, and a whole job goes out in a single message — text, mail, chat. MADE FOR WORKING HANDS A keypad sized for a gloved finger, with the fraction bar. Light theme readable in full sun, dark in the shop. Imperial or metric: inches to the sixteenth, a dimension types as "3 1/2", the way it reads on the print. IN SIX LANGUAGES English, French, Spanish, German, Italian, Polish. HONEST ABOUT WHAT IT IS The values are indicative. They replace neither the applicable codes (ASME, AWS) nor a qualified WPS — they save the ten minutes between the question and the answer. And every result shows where its number comes from. Made by a welder, for the people who set the steel.
