Piping Offset Calculator provides precise dimensions and cut lengths for different types of piping offset spool configurations, pipe sizes, and bend angles. Piping Offset Calculator is designed to be used by draftsman, designers, engineers, and construction personnel.

Piping Offsets have never been easier to calculate. The offset calculator is very intuitive and flexible: the graphical menu is provided to easily select the type of offset you wish to compute. User supplies any three sides and/or angles combination(s).

The user is presented with the solved graphical representation of the offset. The complete graphics include multiple solution views which provide clear, graphical, design and fabrication data. All bend angles, tangents, cut lengths, rise, run, hypotenuse, miter angles, roll angles, inside and outside arc lengths of mitered ells, etc are presented.

User can select 1/4" through 48" pipe sizes, preset bend or ell radius, or the user can also choose a fixed user input numerical radius for those unusual bend radius requirements.

Even though the offset calculator automatically calculates trimmed elbows (per user request), now includes a separate tool to calculate trimmed elbow dimensions.

To learn more about this useful tool, browse www.jplanaux.com or go to you tube and search "Piping Offset Calculator".

Not very accurate

I’ve been in the trade for 13 years and have done these calculations by hand. Still do. This app was fairly accurate if you stayed below 10” for your rise and run. But the travel length the app gives oddly seems to be cut in half of what it actually is. Anything I tried with the rise or run over 10” was just turned out to be the wrong measurement. Don’t waste your money like I did.

Excellent work once again!

This app writer has come out with two amazing apps I have tried and both are excellent. This one is incredible. It has been a tremendous help and has been very effective in saving time when used in conjunction with 3D piping software. It is a MUST have for piping designers. Hopefully he will have some additional apps coming out. If they are half as good as this one and the piping abacus, I want them all. I want to strive to be the complete and total piping designer, with all of the latest and greatest tools at my disposal. These two are a must have! Can't go wrong.

Better than the other one!

I mistakenly bought an app made by a competitor first, it seamed ok at first then an update made it very confusing. So in frustration I purchased this app and wow, it's so simple a stupid pipe fitter like me can use it. Don't look anywhere else, you have come to the right place first. I have now purchased two other apps from this builder and like them just as well. Thanks for making your apps stupid simple!!
