This app allows you to create solutions using the methods and formulas covered in SMACNA’s Round Industrial Duct Construction Standards Manual.
You can select welded or spiral seam duct, english or metric units, particulate information, duct information (material, class, pressure, temperature), external duct design information (insulation, cladding, wind, snow, ice, various live loads such as snow and wind loading, various dead loads such as insulation and cladding, hanger spacing, air temperature, and particulate properties.
Once the information is selected (or manually entered) the app generates several answers and you can select options to consider. You can then create a full engineering report that outlines the procedure used to create the specific solution.
