PipeFab Pro: Offset Calculator

Pipe fitting calculator for pipefitters, steamfitters, sprinkler fitters, and welders—simple offsets, rolling offsets, miters, take-offs, and real cut lengths. PipeFab Pro gives you the jobsite math you need in seconds—without intrusive video ads, without requiring an internet connection, and without a $40/year subscription for math that never changes. Why Pipefitters Choose PipeFab Pro: ───────────────────────────────── ★ REAL CUT LENGTHS (NOT JUST THEORETICAL TRAVEL) Other calculators leave you hanging with theoretical triangle travel. PipeFab Pro automatically deducts standard ASME B16.9 butt-weld elbows (45°, 90° Long Radius, 90° Short Radius) so you know exactly what length of pipe to cut on the saw. ★ TAPE MEASURE FRACTIONS (NO CONFUSING DECIMALS) Mike on the jobsite reads a tape measure, not raw decimals. PipeFab Pro outputs clean 1/16", 1/32", and 1/8" fractions with instant visual tolerance indicators (+) and (-). ★ 100% OFFLINE & BATTERY-SAVER DARK THEME Works deep inside mechanical rooms, trenches, shipyards, and offshore rigs with zero cellular reception. The high-contrast industrial dark theme prevents glare under the sun and saves battery all shift. ★ NO SUBSCRIPTIONS. PAY ONCE, KEEP FOREVER. A calculator does not have cloud server costs—so why rent your own math? Simple Offset and Unit Converter are 100% free forever. Unlock all 9 pro tools—3D Rolling Offset, Miter Cut, Branch Saddles, Flange Bolt Circles, Reducers, Pipe Weight, Pipe Expansion, Hydro Test, and Bolt Torque—with a single one-time lifetime purchase. Core Jobsite Tools Included (11 calculators): ─────────────────────────────────── 1. SIMPLE OFFSET CALCULATOR • Instant Travel, Run, and Multiplier (45°, 30°, 60°, 22.5°, or custom degrees). • Real-time visual dynamic blueprint with dimension lines. • Automatic elbow takeoff deduction for 1" to 12" standard pipes. 2. 3D ROLLING OFFSET CALCULATOR • Calculate compound 3D offsets with Roll (Spread) and Rise. • Outputs True Offset, 3D Travel, Plan Run, and Roll Angle. • Interactive isometric 3D visualizer. 3. MITER CUT & CUTBACK CALCULATOR • Accurate cut angles and cutback marking length for 2-piece, 3-piece, 4-piece, and 5-piece turns. • Visual cutback diagram for marking lines around the pipe circumference. 4. BRANCH SADDLES & LATERALS (FISHMOUTH / COPE) • 90° tee saddles and 45° laterals: branch cutback from peak to crotch. • Heel-to-toe (long point to short point) marking for the cope. • Header hole cut length × width, with branch-cannot-exceed-header validation. 5. FLANGE BOLT CIRCLES (PCD / BCD) • ASME B16.5 flange presets or fully custom PCD and hole count. • Adjacent chord distance, triangulation chords, angular step, and hole orientation. 6. REDUCER LAYOUT • Concentric and eccentric reducers (FOB flat bottom / FOT flat top). • Centerline offset E, slant height, apex distance, and maximum slope angle. 7. PIPE WEIGHT CALCULATOR (ASME B36.10M) • Instant total lift weight and weight-per-foot (lb/ft) or kg/m. • Presets for Schedule 40 standard pipes up to 12". • Supports Carbon Steel, Stainless Steel (304/316), Aluminum (6061), and Copper. 8. INSTANT UNIT CONVERTER • Bidirectional conversion between Decimal Inches, Tape Fractions, Feet, Millimeters, and Meters. 9. PIPE THERMAL EXPANSION (ASME B31.3) • Straight-run growth and expansion loop sizing using Table C-1 coefficients. 10. HYDROSTATIC TEST PRESSURE (ASME B31.3) • Test pressure at 1.5× design (Clause 345.4.2), 90% SMYS limit, and MAWP check. 11. BOLT TORQUE (ASME PCC-1 / VDI 2230) • Target torque T = K × F × d at 50–70% of proof load, with ASME B16.5 bolt presets. 12. JOB HISTORY & REUSE • Saves your last 50 calculations offline.
