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
