A wide variety of round fittings are produced for high pressure including 90, 60, 45 and 30 degree elbows, tees, laterals, reducing laterals, reducers, couplings, end caps, crosses, etc. Fitting ends are made with two inch male sleeves. Standard fittings have built-in slip type beaded couplings.
Gores & Seams:
Lapping of seams are in the direction of air flow. The gore & seams are spot welded sand
internally sealed using high pressure duct sealant.
Fitting ends are made with two inch male sleeves with a stop-bead up to 36” diameter.
1-1/2 times the diameter (long radius) to centerline is standard
Particular attention is given to the entrance for conical tees, straight tees, and laterals. These fittings have a rounded entrance edge. They are not butt-welded, square-entrance contractor-type fittings.
Fittings are machine cut on our State-of-the-Art Vulcan Plasma table, assuring manufacturing tolerance consistency.
Specialty configurations are available upon request. Some examples are as follows: Elbows (75, 15 and other degree angles are also available), wide variety of different radii are available. Flange connections are available by the following, but not limited to: Angle Rings or, AccuDuct, Spiral Mate.
As listed in the current SMACNA HVAC Duct Construction Standards. Other regulatory construction standards are available upon request.
