Product Details
These duct construction standards are intended for use by contractors, fabricators, and designers of air pollution control,
pneumatic conveyance, and industrial ventilation systems.
The 1977 edition of these standards was the first publication dealing with the selection of duct gage and reinforcing
systems for industrial duct applications. While the first edition served industry very well for many years, technology
has continued to move forward, and the Industrial Ventilation and Power Industry Task Force of SMACNA has responded
to our membership’s request to expand and update the original text.We are taking their request one step further
by restructuring the manual and providing supportive software to make the design process more “user friendly.”
One of themain considerations in the development of the newstandards is the opportunity to create a software program
for personal computers that can greatly expand the computational capability of the user and permits an almost unlimited
examination of different construction details and design solutions. A comprehensive review of the old procedures
was completed and modifications implemented to update the technology and make the design procedures compatible
with the computerization effort.
While the new procedures include many of the same assumptions as the original work, a number of new features have
been added:
Microsoft Windows® based calculation software to expedite selection of construction details (software
sold separately)
Four different types of carbon steel and two different types of galvanized steel
Seven different types of stainless steel alloys
Four different types of aluminum alloys
Design capability for high temperature systems up to 800°F (427°C), and higher with design reviewby a specialized
professional
Consideration of wind, snow, ice, and maintenance loads
Expanded tables to include ducts to 96 in. (2440 mm)
Expanded tables to include material up to ½ in. (12.7 mm) thickness
All data presented in both English (customary) and Metric (SI) units
Expanded data for the selection of duct supports
Chapter on the use of spiral lockseam pipe in industrial applications
Accepted industry practice for round industrial ducts
New Duct Class 5 for systems handling corrosives
New chapter on welding
New guide specification for the fabrication and installation of industrial duct systems
Chapter of practical examples with step-by-step calculation instructions
Chapter of flow charts to guide the user in design process
