Pipe Miter Cut Template Generator
Create outside-surface pipe miter and cope layout points with measured-OD, print-scale, code, weld, and hot-work warnings visible
Free pipe miter template screen for pipefitters, welders, and fabrication shop workers. Enter pipe OD by nominal row or measured custom OD, choose a simple miter, multi-piece elbow profile, saddle cope, lateral saddle, or fishmouth cope, and review printable outside-surface layout points. The output is a layout aid only. It does not validate ASME B31 pressure design, miter-bend limits, branch reinforcement, AWS welding requirements, inspection acceptance, cutting safety, or hot-work authorization.

-
Select the layout type
Choose a simple miter, multi-piece elbow profile, saddle/branch cope, lateral saddle, or fishmouth cope. The screen generates profile points only, not code acceptance or final fit-up.
-
Enter measured dimensions
Use the nominal OD row for a first pass or enter measured OD directly. For saddle and fishmouth layouts, enter both the header and branch OD values.
-
Set the angle
For miter layouts, enter the included joint angle. For lateral saddle layouts, enter the branch approach angle. Check the shop drawing and governing code before production use.
-
Print, measure, and test fit
Print at 100 percent scale, measure the reference square, wrap the paper around scrap or test material, and verify fit-up before marking production pipe.
Built For
- Pipefitters screening miter layout geometry before shop or field layout review
- Welders comparing segmented elbow profile lines before checking WPS and inspection details
- Fabrication shops preparing saddle or fishmouth layout points before CAD, template, or scrap fit-up verification
- Maintenance crews planning field modifications only after pressure isolation, gas freeing, LOTO, and hot-work controls are resolved
- Instructors demonstrating how cylinder surface geometry turns into a flat wrap template
Assumptions
- The template is developed on the outside surface of a round pipe or tube.
- Nominal OD rows are cached local rows and must be checked against actual measured pipe.
- No kerf, bevel land, root gap, grinding allowance, weld shrinkage, or tack-up distortion is added.
- Pressure piping, structural welding, hot work, and field modifications require the governing code, permit, and qualified review.
