Pipe Math Pro vs XPipe Pro

Know your travel. Know your cut. Get back to the job. Pipe Math Pro puts practical plumbing calculations and clear pipe diagrams in your pocket. Enter your measurements, see where they belong on the picture, and read the result in familiar tape-measure fractions. Designed by a plumber for plumbers, with the measurements you need close to the diagram and explanations available when you need them. ONE PURCHASE. ALL THE TOOLS. No ads. No subscriptions. No yearly fees. No in-app purchases. The calculations work offline, with no account required. OFFSETS: 22½°, 45° AND 60° • Calculate travel from spread. • Enter the fitting allowance and choose one or two deductions. • See spread, travel, fitting allowances and finished cut length on the pipe. • Read travel and cut pipe as separate results. ROLLING OFFSETS • Enter horizontal and vertical offsets. • Calculate true offset, travel and cut length. • Follow a 3-D pipe diagram showing each measurement. • Choose 22½°, 45° or 60° fittings. SPREAD ALLOWANCE • Keep parallel offset runs equally spaced. • Enter the first pipe cut, spacing and number of pipes. • Calculate the next pipe lengths with fitting allowances. • Work with 22½°, 45° and 60° offsets. PIPE SLOPE • Calculate rise over the pipe run. • Choose 1/16, 1/8, 1/4, 1/2 or 5/8 inch per foot, or use the percentage wheel. • See the high-end rise above level ground. PLUMBING QUICK MATH • Pipe volume per foot, total volume and water weight. • Tank capacity and partial fill for rectangular, vertical cylinder and horizontal cylinder tanks. • Water weight, including an empty pipe or tank's weight. • Water head and pressure: feet, PSI and kPa. • Pipe pressure loss with optional elevation and fittings inputs. • Flow and velocity, in either direction. • Fill or drain time, or the flow needed for a chosen time. • Measurement diagrams, input guidance and formulas. CONVERSIONS THAT FIT THE WAY YOU WORK • Feet and inches to metres, centimetres, or metres plus centimetres. • Reverse the direction in a tap. • Litres, Imperial gallons and US liquid gallons, clearly labelled. • Decimal inches to tape-measure fractions. • A basic calculator for everyday arithmetic. Enter decimal inches, fractions or mixed fractions in supported measurement fields. Displayed tape measurements round to the nearest 1/16 inch; calculations retain their underlying precision. Pipe Math Pro is the new version of Pipe Math. If you already own Pipe Math, this update is included with your existing App Store purchase. Use the actual inside dimensions and fitting allowances for your materials. Water pressure-loss results use the Hazen–Williams model and the selected pipe coefficient.

XPipe Pro works out the numbers a pipefitter needs on the bench and draws the part they belong to, so the figure on screen and the shape in your hands agree. Every answer comes with a scale drawing of that exact assembly, dimensioned where you would put a tape on it — not a stock diagram of something similar. 35 CALCULATORS Assembly and layout: • Two half elbows in one axis — two half elbows in one plane, with or without an insert, solved six ways. • Rolled elbow — a 90° elbow turned about its inlet and a fitting that lays the run flat again, same six ways. • 3D run — a line across X, Y and Z, both angles solved separately, with the box you measure drawn around the pipe. • Elbow cut — an odd angle on an elbow: take-out, heel and throat arcs, chords, heights, and the arcs to mark back from the face you have. • Segmented elbow — a bend from straight pipe: segment lengths, saw angle, and the wave to wrap round the tube to mark the cut. • Branch / fishmouth — one pipe into another, square or skew: length to cut, set-back at up to 24 stations, and the hole in the run. • Eccentric branch — the same joint with axes set apart, each side marked on its own. • Elbow support — a tube cut to stand under a bend, off a torus seat, not a cylinder. • Cone layout — the flat sector for a full or truncated cone, with sheet size, area and volume. • Square-to-round transitions — twelve pieces off one construction, plus a pipe into a pyramid. • Pipe bank — several lines offset together: how far to hold each fitting back so the spacing holds through the slant. Shop and welding: • Dished head — blank diameter and knuckle allowance for hemispherical, elliptical or torispherical heads. • Fillet weld — throat, leg and weld metal for a or z, so a6 and z6 are never mixed up. • Reducer cut, purge gas, slope, pipe mass, pressure test, thermal expansion, cold spring, weld prep, shrinkage, flange studs, support spacing, and a scientific calculator with a full expression parser. WELDER QUALIFICATIONS AND PWHT (NEW IN 2.0) ISO 9606-1 and ASME IX certificates with their range worked out, renewal dates, reminders and a photo. PWHT under ASME B31.3: whether a weld needs it, the temperature and time, and which condition is missing to skip it. PIPE ISOMETRICS Draw a line as you set it out: a direction, a length, the next direction. Elbows and tees place themselves; add valves, flanges, reducers and supports. ISO 6412 symbols, elevations and centre-to-centre dimensions, a bill of materials, and a cut list that flags a take-out it does not know rather than guess it. Out as an A4 or A3 PDF, or as a link another fitter opens. A STANDARDS LIBRARY SEARCHED BY SIZE Type a dimension on its own — 53 — and the library returns every standard that tabulates it, saying why: "in the table · DN 50 · Ø53 × 1.5". A drawing quoting a superseded code like DIN 2463 finds the ISO 1127 that replaced it. 98 standards across PN-EN, DIN, ISO, SMS and ASME — pipe and flange tables among them — plus 239 isometric and drawing symbols from ISO 6412, ISO 4067, ISA-5.1 and related standards. FROM SCREEN TO STEEL Cone, transition, branch and segmented-elbow patterns export at 1:1 — as DXF a plasma table opens directly, or as A4 sheets with a printed ruler, catching a rescaled page before the steel does. MADE FOR THE JOB • A spirit level built in, for when the real one is in the van • Work sorted into jobs — one button makes a finished job a PDF sheet • One backup file for the whole history — no account, no server of ours • Millimetres or inches everywhere, at the precision you choose • 24 languages, switch without restarting, Urdu and Arabic right to left • iPhone and iPad NO ADS. NO TRACKING. NO ACCOUNT. XPipe Pro contains no network code at all. Nothing is collected or uploaded, and it works in flight mode at the bottom of a tank. XPipe Pro is a calculating aid, not a substitute for judgement or the drawings and standards a job is built to. Always check a figure on the steel.
