What is Plastic Ducting
If you have browsed a bit through our categories by now, you most likely realised how many options you have for ducting pipes. Different sizes, shapes and materials are used in making ducting pipes, and each one of them has its features and downsides. According to the application you are building a system for, you should choose the right duct pipes for your project, to make it efficient and durable.
One of these types is plastic ducting. Obviously, it is made out of plastic, more specifically PVC.
Types and Sizes
Plastic ducting is available in two different types. Each one of them is suitable for different scenarios.
Plastic pipe types:
- Rectangular ducting;
- Round plastic ducting.
The difference between the two is their shape. It is what gives one an advantage over the other in the planning process, but we are going to talk about that a bit later. Now let’s get familiar with the most common sizes of those ducting pipes.
Round plastic ducting sizes:
*the most common size is 100mm plastic ducting
Rectangular plastic ducting sizes:
- 110 x 54mm;
- 204 x 60mm;
- 220 x 90mm.
Benefits of using Plastic Ducting
The benefits of using this product over others are a few. First of all, and probably most important, excellent airflow characteristics with minimum air turbulence. The effect comes from the smooth internal bore of the pipes. This goes mostly for the round plastic ducting pipes, thanks to their shape. However, both types are lightweight making them easy to install with less mounting points and connections, compared to other products.
Some types of plastic ducting are also cheaper. When you add that to the less amount of mounting accessories you really can save some money while using PVC ducting. This material is easy to work with, it can easily be cut to size with the use of a saw blade or similar tool. If the plans for the system are correct, the installation is a breeze.
Those ducting pipes are also solid, with thick walls and are rigid enough to withstand light blows and rattles. The losses in pressure, the amount of air that escapes from various holes and connection points of the system, are insignificant. Almost close to none.
Above all that, if you ever need to switch from one type (round plastic ducting) to the other (rectangular ducting) you can easily do so via a special fitting piece called transformer. But why would you need to switch from one to the other in the first place? Well, let’s answer this question in the following paragraph.
This product is probably the perfect solutions for ventilation systems. Most times those systems must be concealed, hidden somewhere in walls, ceilings or even floors. Temperature differences, leaking pipes and bad isolation can easily be reasons for those crevices in the building to have higher levels of humidity. A benefit of PVC ducting pipes is that they are highly corrosion resistant. The moisture in the air which travels through the ducting pipes of a ventilation system is another factor that brings corrosion risk levels way up. If you decide to use steel ducting pipes they will not last long in such conditions.
But if they are all that great, why do we have two options on the market? Why won’t just use round plastic ducting all around? Although round pipes should always be the go-to option, especially for long-range systems, rectangular ducting has one benefit that no other product has. They are more easy to fit in tight spaces. Given the above-mentioned fact that ventilation systems are often hidden in the structure, tight spaces and corners are common. With rectangular ducting, we can fit the system in tighter spots and we can easily run it between pillars and other obstacles. This is why rectangular ducting is used over round ones, even if within one full system. Here is where the “transformer” fittings come in handy.
