Choosing the right type of pipe to build an air duct for your garage
When designing an air duct for your garage, there are a lot of things you need to think about. It has to be able to keep dust and harmful particles out of the air, while also making sure that the inside temperature isn't affected by the air outside. One very important choice you'll have to make is what type of pipe you wish to use for your air duct. There are a few options to choose from, and in order to get the best solution for your system, you need to know a bit about these options.
Spiral welded pipe
Spiral welded pipe is a common type of pipe for air ducts, as it is durable and comes with excellent load bearing qualities, meaning it's very unlikely to break. The spiral construction of the spiral tubing prevents any stress to be put on any sections of the pipe, making it strong. The downside of spiral tubing is that it's a bit more expensive than other options, as the spiral construction takes longer to construct than pipes without that type of welding. However, for a long lasting structure that is unlikely to demand any repairs, spiral ducting is a great option.
Seamless pipe is another type of pipe that is commonly used for air ducting. This alternative can be cheaper than spiral welded pipe, but is also less durable. You also need to be careful with these types of pipes as you're storing them before the actual installation. These types of pipes don't have much vertical strength and can distort or break under the weight of other pipes or material being stacked on top of them. The main advantage with building an air duct using these types of pipes is that they tend to be less expensive than other types of welded pipe.
Longitudinally welded pipe
Longitudinally welded pipe is also a rather common option for building air ducts. This type of welded pipe holds much of the same advantages as spiral welded pipe, but has the disadvantage of not being as horizontally strong as a spiral pipe. The longitudinally welding makes the pipe strong enough to withstand substantial vertical force without bending or breaking, meaning you can stack the pipes before construction without a problem. If you need to apply force on it horizontally, however, you need to be very careful, as the welded sections aren't connected to each other and are weak. If the pipe is handled to roughly when being pushed in place through the wall, it can fold like an accordion.
