When it comes to Single Wall Spiral Duct, contractors typically attach one piece to another on the job site with a Slip Coupling and screws. But, the larger the diameter the more of a challenge it is to use slip couplings…and the quality of connection is rarely good. As a rule of thumb, these contractors […]
RLS = Rapid Locking System Press Fittings are a solution for joining together tube without use of solder/flame for high pressure refrigerant applications RLS Press Fittings offer a simple, effective and economical method to create leak-free copper tube connections. Made of soft copper for easy crimping, RLS Press Fittings can connect to both soft copper
Installing fiberglass pipe insulation takes skill and patience. It can be especially time consuming when you need to create a customized fit around small bore pipes and fittings. Filleting insulation to fit small pipes and joints can be inefficient and labor intensive and a poorly placed fillet can result in wasted materials and be costly. That’s why Owens Corning has created an

In TDC, TDF and Ductmate fittings there’s usually an open gap of remaining V Notch in between where the duct is joined with the corner. This gap needs to be sealed, otherwise it can become a point of leakage when TDC, TDF or Ductmate is used as the transverse joint connection. The Duct Shop is typically

Linacoustic RC (Reinforced Coating) is a flexible glass duct liner, manufactured using resilient glass fibers bonded with a thermosetting resin. The smooth airstream surface is protected with a durable glass-mat facing that is coated with an EPA-registered antimicrobial agent, Permacote. This improves moisture resistance and helps protect the product against damage from mold or fungi
The common method for “turning the drive” is by means of bending the edge of sheet metal “up and over” to form a 7/16″ open hem 180 degrees using either a manual or pneumatic cleatbender. But there’s another option…Rollforming. Shops with a Coil Line are the best candidates for a Drive Turn Rollformer if the Coil Line has

Since Rectangular Duct fabrication revolves around the Longitudinal and Transverse profiles, the “must have” machines are mostly ones that fall into one of those two categories, so here we go… #1. Pittsburgh Machine: This machine rollforms the female pocket seam and since Pittsburgh is the universally accepted lock in commercial HVAC ductwork, every shop has a standard

The choice of Oval by engineers is driven by ceiling height factors on jobs that would otherwise be round Spiral. By taking Round Spiral and pushing/pulling it into an Oval shape, the engineer can get that same round diameter in an equivalent Oval shape and avoid ceiling height restrictions that the round pipe would encounter. We’re seeing

It’s a common source of confusion and it’s not just because they have similar names. These two machines look similar—two handles, close in size, and mount on a stand. Because each is an essential machine for Rectangular Duct Fabrication, every Sheet Metal shop making duct has one—and from a distance it’s easy to mistake one for
