Galvanised Spiral Duct - 1 Metre Length - 100mm

Product Information

Typically, spiral ducts are 3-6 meters in length, while rectangular ducts are only 1-1.5 meters. The connection of two spiral ducts requires just one joint, while connecting conventional rectangular ducts often necessitates a separate double flange system. There are two types of spiral ductwork: welded and seamless. Welded spiral ductwork is made by welding together the coils of metal that make up the pipe. This type of spiral ductwork is less expensive than seamless spiral ductwork, but it is not as strong and can leak if not installed properly. Seamless spiral ductwork is made by drawing a single piece of metal through a series of dies that form the coils. This type of spiral ductwork is more expensive than welded spiral ductwork, but it is stronger and less likely to leak.

Please be aware that at this moment in time the lead time for custom manufactured items is slightly longer than usual due to high demand. Bends (elbows) for Spiral Ductwork, Concentric Reducers, Curved Boots, Pressed & Fabricated Saddles, Flat Shoes, Equal Tee pieces, Y Pieces, Birds Beaks, End Caps (mesh & shallow), Roof Cowls, Split Rings & Silencers (Attenuators) Quieter: Spiral ductwork is also much quieter than traditional ductwork because the spiral shape helps to reduce noise as air moves through the ducts. This can be a major advantage if you live in a noisy area or if you have young children in your home who need to sleep.That depends on the material and the way the spiro tube is made. Our steel pipes are heat-resistant. The various fittings can also be connected airtight. Aluminium and plastic spiral ducts are less resistant to higher temperatures Better Sealed Joints. One of the biggest issues with most HVAC ductwork is getting a good air seal at connections and joints. Anywhere from 25-40% of the air in forced air systems is usually lost through leakage in ducts that are in attics or crawl spaces. Spiral duct systems not only have no joints along the length of each section, which isn’t true of sheet metal ductwork, but have a seal at the joints that meets or exceeds the highest industry air-leakage standards.

It is well known that the wind resistance of a circular duct is much smaller than that of a rectangular duct. The advanced spiral pressing rib technology enhances the strength of the spiral air duct to withstand pressure. It can be difficult to know which type of spiral ductwork is best for your needs, but with this guide, you’ll be able to make the right decision for your home or office. Spiral ductwork can really finish off the look of a commercial space, I’ve seen polished or painted spiral ductwork really add to the aesthetic of an office in my time as an HVAC design engineer in New York City. Spiral ducts can be used to replace existing ductwork quite readily. If they are used to replace the branches off the main trunk – whether rectangular or round – the same size spiral duct can simply be used in place of whatever was used before. If the main trunk (usually rectangular) is being replaced, there will be a flat oval shape of the right size spiral duct that can be used in its place.The appearance Isn’t for every interior design style. No matter how nice it may look to some people, others will always think it has that “not finished” look. For many people, HVAC ducts are something that should be kept out of sight – not hanging over their heads! The upper and lower rolls of the spiral duct machine are made of Gr15 steel, the quenching hardness reaches HRC58-62 degrees, and the belt mold is made of elastic steel. Pneumatic system Simple to Clean. The approved tools and methods for cleaning spiral ducts are easily obtainable, economical, and effective. The fact that spiral can be found in galvanized steel, aluminum or copper means it can accent many different interior design schemes. It can also be painted any color to either match or accent other colors in the home – even a different color in each room. Of course, spiral ductwork is more than just pipe and fittings, a complete ventilation system, depending on the project, may consist of the following components:

Spiral ductwork is also well-suited for use in tight spaces. Unlike traditional rectangular ducting, which can take up a lot of space, spiral ducting is much more compact. This makes it ideal for applications where space is at a premium. Its round shape allows for smooth airflow with less resistance than rectangular ductwork, and its spiral design helps to reduce noise levels.More Difficult to Install: Another downside of spiral ductwork is that it can be more difficult to install than traditional ductwork. This is because the spiral shape can make it challenging to get the pieces of ductwork to fit together properly.
