Introducing SMACNA’s Round Industrial Duct Construction App

Mar 26, 2015

Round industrial duct construction calculations just got a whole lot easier for SMACNA members.

Now there’s an app for SMACNA’s “Round Industrial Duct Construction Standard” (RIDCS). This powerful app, available today, is actually Web-based. Best of all it is free to SMACNA members.

Click here to access the App. Scroll down to “SMACNA’s Round Duct Construction App.” Select “Web Version.” Login to your member’s only account and you will automatically arrive on the App landing page.

The new App solves the many complicated calculations for duct fabrication. The user can create an infinite number of solutions using the methods and formulas covered in the “Round Industrial Duct Construction Standard.”

A tremendous time-saver, this App enables the designer to select:

  • Spiral or welded duct
  • Duct material
  • Multiple live loads, snow and wind loading
  • Various dead loads, insulation
  • Hanger spacing option
  • Air temperature
  • Particulate properties

This super-charged App can generate multiple answers that conform to the “Round Industrial Duct Construction Standard.” Once all appropriate selections are final, it generates a detailed, full engineering report outlining the formulas used to create the specific solution.

All of this and more is free to SMACNA members.
