The Sheet Metal and Air Conditioning
Contractors’ National Association will present a series of three Webinars on
how to construct HVAC rectangular and round duct. The series will explain how
to construct the ducts so that they are compliant with SMACNA’s “HVAC Duct
Construction Standards-Metal and Flexible” manual.
To sign
up, visit the Education section of the SMACNA Web site atwww.smacna.org. Participants will earn $50 in
savings if they sign up for all three Webinars in the series. Registration for
all three is $385. One Internet computer registration fee allows unlimited
participants at the same site. For each separate Webinar, registration is
$145.
“Rectangular Duct External Reinforcement” will be held on April 21 at 11 a.m. This
Webinar will cover basic definitions used to properly describe rectangular
duct, limits and proper application of various joints and seams, and how to use
SMACNA’s standard to determine proper construction options. Construction options
to be discussed will include how to select the proper gauge and the proper
external reinforcement angle. This presentation will cover duct up to 120
inches by 120 inches and address positive pressure and negative pressure
applications. This is the first session in a three-part
series.
“Rectangular Duct Tie Rods, New Tables (TDC/TDF),
and Rectangular Duct Over 120 Inches” will take place on May 5 at 11 a.m. This
presentation will cover how to properly determine tie rod options for
rectangular duct, positive pressure and negative pressure options, and the
effects of using heavier gauges on tie rod choices.
“Round
and Oval Duct, Hangers, and Casing Construction” will take place on May 19 at
11 a.m. This program will cover round and oval ducts including the basic
definitions used for round and flat-oval duct, limits and proper application of
various joints and seams, use of the “HVAC Duct Construction Standards-Metal
and Flexible” to determine proper construction for spiral duct and longitudinal
seam duct. Examples will cover determining the proper gauge and the proper
reinforcement. Positive and negative pressure construction options are
explained. It will also cover how to select the proper components for duct
hangers. Casing construction will also be addressed. This is the final session
in a three-part series.
