Pipe Miter Cut Template Generator
Choose the layout type, enter the measured pipe size and angle, then check the printed scale.
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.
