- For
- Pipefitters, welders, apprentices, and field crews
- Worth noticing
- Six named calculators pair results with transparent substitutions, while cut sheets retain job details and field notes locally.
Field notes
The page organizes six trade calculations around concrete inputs such as takeouts, pipe diameter, wall thickness, rise, roll, and angle. It also exposes a job-record workflow with fields for the line or pipe, fitting or source, verifier, and field notes. The site describes local saving and printing for cut sheets, while explicitly limiting the geometry viewer: it is not presented as a code-compliance model and still requires field verification.
