SMACNA HVAC DCS 3.1

This app offers SMACNA compliant options for rectangular ductwork ranging in size from 1 inch to 120 inches, suitable for applications with pressure levels from -10 to +10 inches of water column.

The app presents scenarios limited to joint lengths of 4, 5, and 6 feet, as well as specific transverse connection options including T1 (flat drive), T5 (flat slip), T10, T11, and T12 (standing slips), and T25 a or b (TDC/TDF). It also covers intermediate reinforcement possibilities with spacing options ranging from 6 to 2 feet.

Furthermore, users will find details on internal and external reinforcement choices, such as EMT conduit tie rods for internal reinforcement and angles for external reinforcement. The app guides users with comprehensive information, aiding them in selecting alternatives from the SMACNA Standard if needed.

Upon calculation, the app provides a detailed written description of the duct along with a graphic depiction. Users can conveniently view the report on-screen or share it via email.

While not exhaustive, the app doesn't encompass every solution outlined in the SMACNA Standard and may lack some specifics like guidelines for proper reinforcement attachment. It is designed to complement the use of SMACNA’s HVAC Duct Construction Standard.
