SPOT Flanges are an economical option for joining double-wall round and flat oval spiral pipe and fittings where the size or an installer preference requires a flanged connection. They are roll-formed from 18-gauge galvanized material, then factory mounted on our spiral pipe and fittings Eastern Sheet Metal > HomeEngineers, code officials and owners are taking notice and questioning the use of ducted HVAC systems. There is a simple ducted solution, factory fabricated spiral duct and fittings. It has long been recognized that spiral pipe systems leak a great deal less than comparable rectangular systems.
Dual wall round and oval duct with interstitial fiberglass insulation has been the gold standard for providing both at a reasonable price. In the past few years there has been concerns raised about the presence of fiberglass in the airstream creating a health hazard. Flat Oval Duct Oval Spiral Duct - DC Duct & Sheet Metal LLCOval duct resembles a spiral duct that has been stretched sideways making the diameter of a large pipe thinner without reducing the ceiling height while maintaining the CFM of the ductwork. It doesnt have sharp edges like rectangular duct, but it is flat on the top and bottom, meaning that it can lay directly against the ceiling like Flat Oval Spiral Duct - NJ - Airside SheetmetalAirside Airside Sheet Metal Fabricators, Inc. produces flat oval and double wall ducts from 16 x 6-inches to 59 x 18-inches and related fittings.

SPIRAL DUCT & FITTINGS - Eastern Sheet MetalExample:Change 18 x 34 flat oval to a smaller size. To change the size, first note the equivalent round size listed for 18 x 34, it is 25.7. This means 18 x 34 flat oval spiral will have the same friction loss as 25.7 round spiral duct. Next, find 25.7 for a flat oval with a smaller minor axis.
