InsuLayout Pro

Lay out insulation cladding the way the shop does it — from the insulation's real outside diameter, not the pipe's. InsuLayout Pro is a layout tool for industrial insulators and tinners. Pick the pipe size, the wall, and the material; it gives you the flat pattern, the ordinates, and the file for the table. SIZED BY BORE, NOT PIPE OD Insulation is ordered as bore × wall. Rigid materials (calcium silicate, cellular glass, perlite) step up one size; soft materials match the pipe; traced lines go oversize. InsuLayout Pro resolves the actual outside diameter from the ASTM C585 table and lays the pattern out on that — the difference is over an inch of stretchout on a plain 8" line, and about four on a traced one. Every result shows where the number came from and warns when it had to estimate. FITTINGS • 90° and 45° gored elbows, 3 to 7 gores • 90° tee and 45° lateral • Bevel / mitre • Concentric and eccentric reducers — true developments, not approximations • Rectangular box and duct wrap WHAT YOU GET FOR EVERY FITTING • Flat pattern on screen, with lap seam and mirror • Ordinate table in shop fractions (to 1/16") or millimetres, with Copy All • Bench Layout Guide: step-by-step marking-out with this job's own numbers • 3D fitting proof built from the same development as the cut pattern — morph it flat to formed, orbit it, cut it away to see the wall against the pipe • Material takeoff: cladding area, linear feet, pieces of metal, bands and screws FILES FOR THE TABLE • DXF (AutoCAD R12) with the cut outline and ordinate lines • Plasma G-code with kerf offset and safe-Z • SVG Files go straight to the Android share sheet — email them to the shop or drop them on a stick. 2D SHEET NESTING Queue patterns from the layout tab and pack them onto 4×8 or 4×10 sheets or 36" / 48" coil, with kerf, rotation, multi-sheet overflow and scrap yield. REFERENCE • Sizing chart, imperial NPS and metric DN, with the C585 insulation OD, circumference and stretchout • Materials and jacketing: temperature limits, thermal conductivity by mean temperature, the ASTM and CGSB designations that apply (C533, C547, C552, C591, C1729, C1767, C1879, C450) • TIAC Best Practices references, cited by section WORKS WHERE YOU WORK Everything runs on the phone. No signal needed in the plant. No account needed — sign in only if you want to. Imperial and metric. TinnerAI, the built-in assistant, is an on-device rule-based helper for quick sizing questions. It does not connect to any AI service. Your saved jobs stay on your phone. They are not uploaded anywhere. Built by a journeyman insulator. Sizes NPS 1/2" to 36" (C585 bore table to 22"; larger sizes are laid out geometrically and flagged).
