Woodworking shop dust collection systems are designed for all equipment hookups to be drawing their recommended exhaust flow rates at any time the system is operating. Yet, it is the outer shell that determines gauge, reinforcing and construction, as well as defining how a duct fits within the physical constraints of a building. The SMACNA manual will have you increase the gauges or add reinforcing to limit deflection. Round Metal Duct Pipe - Make your next HVAC project a success with the help of this pipe, featuring galvanized steel and a simple design for quick and secure installation. 2. As a result, spiral duct systems usually weigh 30% less than equivalent rectangular duct systems — less material! When sweeping up the shop floor, you close the blast gates on the shop equipment, open the blast gates to your floor sweeps, then turn your dust collector on. Round ducts have virtually no wall deflection in normal operating conditions, and the helical spiral seams strengthen the duct even more. If your round air ducts run below the joists, lay one insulation batt on top of the duct. Without spiral round duct, here are a few of the things that could happen. 2 820k return air 790 draw bands flex duct elbow 714 damper 090a angle round to oval boot 012 oval stackhead round duct ... 12" pipe 10" pipe 9" pipe length gauge item# 2' 24 140209 2' 26 130209 2' 28 120209 5' 24 140509 5' 26 130509 5' 28 120509 ... 12-in x 60-in Galvanized Steel Round Duct Pipe.

Round pipe can be used as a main trunk line or branch line, as well as in return air situations. Rectangular duct meeting the required Seal Class A is expected to leak 50% more than the allowance. You’re going to get more turbulence, and turbulence is bad – you don’t even have to be an engineer to know those square corners of rectangular ductwork cause far more turbulence than no corners (round) or rounded corners (flat oval). Flange Insert Box with Gasket ... 12 x 12 x 8 in. and published articles. Rectangular connections and openings should be avoided because of their tendency for corner leakage. Thickness — standard 1” and 2” annular spacing. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. Model #GV0436-A. We’re not making this up! Whether dealing with how much an assembled length of duct deflects (hanger spacing and seismic bracing) or how much the walls of a duct deflect (limiting metal fatigue, low-frequency noise generation and how the duct may impede other items within the building), the goal is to keep a duct system as static and motionless as possible. Branch fittings entering the trunk directly opposite each other (“crosses”) should not be used. Lengths of duct channel can be joined together using a male connector. For the larger primary trunk ducts, removing a section for cleanout is less desirable and practical. First of all, you have to seal the longitudinal seams of the rectangular duct. If a joint is designed for disassembly, pre-punched angle rings can be used, and the flanges bolted together. Where ducts are exposed to view, insulation is concealed for a more pleasing appearance. The Advanced Energy Design Guides were written by your fellow engineers, not a trade organization or some contractor that bought a coil line and needs to get the most use from it. 4001 Mark IV Parkway Fort Worth, TX 76106 Phone: 817-336-2311 Fax: 817-625-0756 And at the end of service, virtually 100% of galvanized steel ductwork can be recycled. No painting required, will last years outdoors. Galvanized steel is one of the most recycled materials on the planet. 10. Use insulated duct or duct board in unheated spaces. Countless real-world examples where a contractor or manufacturer converted a mostly rectangular duct design to round and flat oval spiral duct, have proven you can get better performance at a better installed cost. You’re going to need more insulation – it’s going to take more square feet of insulation to cover the increased perimeter/surface area of rectangular duct. But when you leave them off, you are usually going to end up with poor-performing and costly rectangular duct. Polyvinyl Coated (PCD) Most HVAC-grade fittings and assemblies use tack-welds, screws or rivets that are then sealed with mastics. They should be spaced a maximum 12 feet apart for ducts 12” diameter and smaller, and maximum 20 feet apart for larger diameters.

They actually are “prerequisites” — preliminary requirements to get any level of LEED certification. Stainless Steel — 304L and 316L More than once, we’ve been consulted on jobs where HVAC-grade duct was installed and subsequently damaged. Perforated metal with erosion barrier – standard perforated material with an additional protective layer of Mylar between the insulation and the perforations opening into the airstream. The equivalent diameter is the diameter of a circular duct or pipe that gives the same pressure loss as an equivalent rectangular duct or pipe.. Their recommendation for Ductwork Design and Construction is: “Low-energy use ductwork design involves short, direct and low pressure drop runs. Do you see where we’re going with all this? Installation labor skews even more in favor of round duct. In Texas, we use the ANSI/ASHRAE/IES It is important to note that the dynamic airflow performance of a duct system is based on the inner shell, and most duct sizing on mechanical drawings are I.D. This is the good part. One end of each piece is crimped for easy fitting of consecutive joints or to sheet metal fittings and flexible duct. Operating Temperature — up to 250°F That’s most often referring to the “2005 SMACNA HVAC Duct Construction Standards – Metal and Flexible”. Spiral Pipe Gauge We manufacture spiral pipe in 18, 20, 22, & 24 gauge galvanized metal. The insulation is protected from external damage — a critical concern for ductwork on rooftops and out of the building envelope. The product is a high-density fiber glass board with a factory-applied black acrylic coating applied to the surface and transverse edges, JM’s Permacoat®. In woodshop collection systems, the additional sources of leakage are the slide blast gates and cleanouts. Since 1981 Spiral Pipe of Texas (SPOT) has The table is based on the ducts friction loss formula.. But a system using spiral lockseam construction will typically use lighter-thickness materials, with diameter/thickness ratios of as much as 1800. Deliver more air with less static pressure buildup with round pipe. However, space (height) restrictions may require flat oval ductwork to achieve the low-turbulence qualities of round ductwork.”. Though sometimes specified, they make duct assembly with slip-fit transverse joints more difficult, create thermal bridges between the interior and exterior of the duct, and have a negligible effect on actual R-value. Perhaps we should pause a moment to let these numbers sink in. The number of fittings should be minimized and should be designed with the least amount of turbulence produced…. But they had three problems — energy was expensive, raw materials were also expensive and often in short supply, and there was a Tapered body transitions are required, and a maximum 30-degree branch angle is preferred. Duct Outlet 14" x 14" Ceiling Box, w/ 12" Round Collar - Connects Register Vent a… So, here we have a product — spiral duct — that uses less energy, less material and less labor than other methods of transporting air. In actual practice, insulation compression is more of a concern for larger diameters of duct where double-wall flanges are typically used for transverse connectors, eliminating any need for spacers. Fitting dimensions (elbow centerline radii, tee fitting length, tap clearance to end, etc.) 12" Snap Lock KD Galvanized Metal Duct. x 5 ft. Beaded Round Metal Duct Pipe Description. It is an important first step in promoting “green” construction in commercial buildings. And ASHRAE has worked extensively to help its’ members achieve these goals by compiling research and assembling cost feedback that might be impractical for a single engineering firm to do.

Frankly, one of our greatest concerns we try to prevent is unintentional damage caused by the users. One end of each piece is crimped for easy fitting of consecutive joints or to sheet metal fittings and flexible duct. They create turbulence within the duct, leading to higher pressure drops and unpredictable transport velocity performance. For round and flat oval spiral ducts, that They also have less-efficient airflows and corners where particulate can be trapped. Solid – standard metal liner in gauges and construction to contain the insulation and maintain concentricity and structural integrity. ... Click to add item "Heating & Cooling Products 30 Gauge Round Metal Duct Pipe" to the … Bacteria Resistance — no growth (ASTM G22), The slightly-less-short answer is: “If you are not using spiral ducts from Spiral Pipe of Texas, then you aren’t really green at all.”. The result is PhenoliDuct. Most HVAC duct systems use “barrel” type fittings where the branch enters a constant-sized trunk. You’re going to need more hangers/supports – about 50% more. regulations and compliance standards we work under. And with less inherent leakage, you won’t need to produce as much air to start with. Log In for Pricing; 10203126. Stronger than other pipe – Our pipe is up to 20% stronger than smooth pipe systems of the same gauge, due to the added spiral reinforcement. This fits your . Caps on the through-end of branch fittings should be the same diameter as the trunk duct. A round duct experiences only about 40% of the wind force a comparable rectangular duct would see.
