Pipe Trades Pro: Offset Calc

**Cut it right the first time. Stop wasting expensive pipe, guessing fitting takeouts, and burning fabrication hours.**

Pipe Trades Pro is the modern, high-contrast digital blueprint calculator built specifically for commercial pipefitters, steamfitters, industrial welders, plumbers, and sprinkler fitters.

Whether you're running 4" Schedule 40 carbon steel in an industrial refinery, fitting copper hydronic lines in a mechanical room, or fabricating high-pressure stainless spools in the shop, Pipe Trades Pro calculates exact travel, fitting takeout deductions, and precision cut piece lengths instantly.

### CORE FIELD & FABRICATION FEATURES

1. **PRECISION 2D SIMPLE OFFSET BLUEPRINT**
- Enter your Set and Run to calculate exact center-to-center Travel and true Cut Pipe Length.
- Interactive real-time blueprint diagram visually maps your offset angle, fitting centers, and fabrication run.

2. **INTERACTIVE 3D CAD ROLLING OFFSET ENGINE**
- Compound rolling offsets made simple: enter Set and Roll to compute True Offset, True Diagonal Travel, and Roll Angle.
- Full 3D interactive isometric spool model: 1-finger drag to orbit (pitch/yaw), 2-finger pinch to zoom, and quick-snap camera presets (ISO, Top, Front, Side).
- Full-screen CAD inspection view with zoom controls (100% to 200%) for jobsite fabrication verification.

3. **ASME B16.9 & B16.5 FITTING TAKEOUT DATABASE**
- Center-to-face and takeout deductions for standard industrial fittings:
- Butt-Weld Long Radius (1.5D ASME B16.9)
- Butt-Weld Short Radius (1.0D ASME B16.9)
- 150# Weld Neck Flanges (ASME B16.5)
- 300# Weld Neck Flanges (ASME B16.5)
- Socket-Weld & Threaded Fittings
- Instant angle presets for 90°, 45°, 60°, and 22.5° elbows, plus custom odd-angle calculations.

4. **COMPLETE ASME B36.10 & B36.19 PIPE DATA HANDBOOK**
- 100% offline dimensional tables for NPS 1/8" through 36".
- Complete schedules: Schedule 10, 40, 80, 160, and XXS across Carbon Steel and Stainless Steel.
- Key engineering specs: Outside Diameter (OD), Wall Thickness, Inside Diameter (ID), Empty Pipe Dry Weight (lb/ft or kg/m), and Water-Filled Loaded Weight for safe rigging and pipe hanger sizing.
- ASME B16.5 Flange dimensions (OD, thickness, bolt circle, bolt count & bolt size) and Tee run/outlet dimensions.

5. **SPOOL CUT LISTS & 1-TAP PDF SHOP EXPORTS**
- Save offset calculations directly to your active Spool Cut List on site.
- Review cut dimensions, fitting types, schedules, and total takeouts before torching or cutting.
- Export clean, professional 1-page shop-ready PDF Cut Sheets to email, print, or share directly with apprentices, foremen, and fab shop fitters via native share sheets.

6. **FRACTIONAL TAPE KEYPAD & ROOT GAP COMPENSATION**
- Enter measurements naturally using a trade-standard fractional keypad (1/16" and 1/32" precision) with feet (') and inches (").
- Built-in Root Weld Gap deductions: select 1/8", 3/32", 1/16", or 0" (none) to subtract weld gaps from pipe cut lengths automatically.

7. **100% OFFLINE IN THE FIELD — NO ADS, NO SUBSCRIPTIONS**
- Engineered to work without cell coverage in deep basements, industrial tanks, refinery trenches, and remote mechanical vaults.
- No account creation, no login walls, no ads, and no recurring monthly subscriptions.
