ATT Calculator


Why would any software company give away software for free?

We want increase our name recognition in the tube fabrication market, and I feel that this is the best way to do it. This program can be thought of as our electronic "business card". So, feel free to copy the software and pass it along to your friends and colleagues. If they have access to the web, then please let them know that this software is available for downloading without charge.

The calculator contains a set of hard-to-find math tools that are used often by tube fabrication engineers. Our plan is to on adding new features to this program from time to time, so you may want to check our web site periodically for the ATT Calculator version. Every time we add new features, we will also increase the version number so you can know if you need to perform a new download. We want your suggestions for future versions, so please let us know if you have ideas for new features.

Finally, in order to give credit where credit is due, I want to publicly thank Rod Malone (TRU-VAL TUBING, Waterford, Michigan) for giving me the idea for this calculator.

A new Tube Flattening section has been added to the Advanced Tubular Technologies Calculator. It is designed to aid tube and pipe fabricators in determining how to set up tooling to create a flattened area on a tube.
The Foot-Inch Sum Calculator allows you to add multiple distances in the Foot-Inch-Fraction format without the hassle of making the different distance units common
The tangent distance is the distance from the tangent point of a bend to its intersection point. Click on the image of the Tangent Distance page to see a close-up of the image. The image will visually demonstrate the tangent distance.
The calculator uses the Radius and Bend Angle values to calculate the tangent distance value immediately.
​The arc length is the length of an arc of a bend. Click on the image of the Arc Length page to see a close-up of the image.
The calculator uses the Radius and Bend Angle values to calculate the arc length value immediately.
​The Conversion Calculator converts values from one unit to another using a pre- programmed multiplier value.
To convert from millimeters to inches, select the Millimeters to Inches conversion from the pull-down list and then enter a value in the "From Millimeters" box.
​The first Right Triangle Base Calculator calculates the values of the two bases of the triangle given the hypotenuse length and the hypotenuse angle.
The second Right Triangle Base Calculator calculates the values of the hypotenuse and one of the bases of the triangle given the other base value and the adjacent angle.
​The Calculator page has the same functionality as the normal Windows calculator
Have you ever needed a calculator "right now", but left yours in the brief case, in the car?
Click on this page and use the Advanced Tubular Technologies calculator or load the standard Windows calculator.

​Standard Windows Commands

Every calculated value in the ATTCalc program can be copied to the Windows clipboard so that it can be used in other Windows programs.

Also, using the clipboard, you can solve for a value in Millimeters and then copy the result value to the Conversion page for conversion to Inches, or Feet, or whatever.

To COPY a value, select that value using the mouse or the shift key and then press Ctrl-C.

To PASTE a value to a box, select the edit box where the value is to be placed and then press Ctrl-V.

To CUT a value in an edit box, select the value and press Ctrl-X.

DOUBLE-CLICK on a value to select a word in an edit box automatically
