XPipe: Pipe Fitter Calculator

Rolling offsets, travel and cut lengths in inches and fractions — with a scale drawing for every answer. 35 pipefitter calculators, piping isometrics and ASME standards, all offline.

35 CALCULATORS
Offsets and rolling offsets, half elbows and turned elbows, elbows at any angle, miter bends, square and eccentric branches, elbow supports, cone and square-to-round layouts, pipe banks, dished heads, fillet welds, reducers, purge gas, slope, pipe weight, pressure test, thermal expansion and more. Pick a calculation by what you know.

HOW TO WORK OUT OFFSETS
A step-by-step guide with drawings and the sum under every step: offset, rolling offset, cut length, half elbow from a 90° and the insert.

PIPING ISOMETRICS
Draw the line the way you run it: direction, length, next direction. Elbows and tees place themselves. Valves, flanges, reducers, supports and symbols from the standards library, turned around the pipe. Slope, field welds, photos and videos, a 3D view. Bill of materials, cut list, weld log, a Letter or 11×17 PDF sheet (A4 and A3 too), PCF and 3D DXF, a link for another fitter.

LASER MEASUREMENT
A cross-line laser takes the position of two pipes and the app suggests the connection, with elbows and cut lengths, in 2D and 3D. Open it as an isometric or add it to an existing one. A Bluetooth distance meter puts its reading straight into the run length, and a run measured on site is marked as measured.

FROM SCREEN TO PLATE
Cone, transition, branch and miter layouts at 1:1: DXF for the cutting table, or Letter sheets with a check ruler.

STANDARDS LIBRARY
98 ASME, ISO, DIN, PN-EN and SMS standards, searched by size alone, plus 239 drawing symbols. An old standard leads to the one that replaced it.

WELDER QUALIFICATIONS AND PWHT
ISO 9606-1 and ASME IX certificates with the range worked out, dates, reminders and a photo. Post-weld heat treatment to ASME B31.3.

WORKSHOP
Favorite calculators on the home screen, a scientific calculator with a dated history, a spirit level, jobs with a PDF summary and one backup file.

ON IPHONE AND WATCH
Apple Watch with measurements and offsets, Siri works out an offset, tools on the Lock Screen and in Control Center. A measurement link opens without installing the app, and a label with a QR code prints on a Niimbot printer. An isometric can be read off a CAD PDF.

NO ADS. NO TRACKING. NO ACCOUNT.
Everything works offline. Inches with fractions to 1/64, or millimeters, units and standards by country, 29 languages. iPhone, iPad and Apple Watch.

XPipe Pro is a calculation aid, not a substitute for judgement or for the standards an installation is built to. Always check the result on the material.
