Ducting insights – Silicone hose – What are its uses?

Ducting hoses come in all kinds of materials, designs and sizes. In most cases the material used to create a hose dictates its capabilities and the applications it is used for. A huge variety of materials are used to make ducting hoses, but silicone stands out as a result of its unique and useful properties. Not all materials are suited to handling high temperature air, steam and toxic fumes, but this is an area where silicone has the edge on other hoses.

Silicone is one of the best materials for high temperature ducting. Most silicone hoses have an extremely high maximum temperature of about 500 degrees Fahrenheit. This ability allows silicone ducts to remain effective, even when they are in hot environments or have extreme heats passing through them. Another area which silicone hoses excel in is the handling of caustic air, fumes and chemicals, which might be harmful to other ducting materials. Having this level of resistance is vital in some situations. For this reason, silicone ducting hoses are extremely popular with companies requiring equipment for industrial settings and specialist applications.

Different variations of silicone are used in ducting hoses, with the type depending on the specific product it is used in. For instance, there is single-ply silicone, along with reinforced double-ply products. Some hoses are also reinforced with fiberglass. Those reinforced products usually have even greater capabilities, such as working temperature ranges reaching up to 750 degrees F. Most silicone hoses have a reasonable degree of flexibility to them, but are not necessarily designed for constant flexing. They are usually best suited to settings where repeated movement is not required. But silicone hoses provide some of the very best options when it comes to high-temperature resistance ducting in harsh industrial applications.

Ducting insights – Duct Hoses – Defining what they are

At its core definition, a ducting hose is tube-like piece of equipment, with an opening at each end, which is made to transfer something from point A to point B. But this is a broad and over-simplistic term which does not properly explain the features and functionality of Rubber-Cal’s ducting hoses. These ducts are made specifically to move a range of materials. This range includes five categories – air of varying temperatures, dust and other fine particles, abrasives, larger non-abrasive materials, and fumes.

There is no one ducting hose product which will be perfectly suited to each different type of material movement. A wide variety of hoses are available, all with different designs and made with different materials, and all boasting different capabilities. Hose materials include PVC, coated polyester fabric, neoprene, silicone, thermoplastic rubber, aluminum, stainless steel and more. Each will provide different qualities. For instance, PVC ducting can provide a high degree of flexibility, while stainless steel is ultra strong and rigid. Some materials provide a higher working temperature, while others handle exposure to chemicals. To ascertain what kind of duct is needed in any particular setting, you need to know what will be travelling through it, what temperature it must be able to handle, whether it needs any resistance to chemical exposure, whether it will be used with positive or negative pressure, and what size is needed in terms of length and diameter.

In most cases, the open ends of the ducting hose are attached in place using a connector, clamp or belt. The applications for a hose can include everything from transferring air within an air conditioning system, sucking up sand, pebbles and other small debris and abrasives, to ventilating harmful fumes. In each of these applications – and many more – the hose itself does not have any powers of positive or negative pressure. It is simply there as a conduit, providing the channel to transfer a material from A to B.

Ducting Insights – Flexible Hose – How is it measured?

One of the key aspects that you need to establish when choosing the correct ducting hose is the size which is required. But how do you measure it? When looking at a ducting hose, there are two important measurements – the length and the inner diameter (ID). The length will probably be self-explanatory to most people, referring to the measurement from one end of the hose to the other. With that said, there is a method to making this measurement which sometimes catches people out, because a lot of ducting hoses are very stretchy with a high rate of compressibility. As a result, the length should be measured when the hose is fully stretched out and pulled tight so that there is no slack. This is the industry standard for ducting hose length measurement.

The inner diameter is a little more complex. This is the measurement across the opening at the end of a ducting hose. The inner diameter is established by measuring across the circular opening at its greatest point. There is a distinction between outer and inner diameter, but Rubber-Cal uses the inner diameter measurement for all hoses. The inner diameter measurement is taken from inside the duct walls. An outer diameter measurement would be slightly larger, taking into account the width of the walls themselves.

When deciding what size of hose you need for any given application, it is important to remember that the inner diameter of a ducting hose should be the same as the outer diameter of the equipment or opening that you want to attach it to. Make sure you get the correct length and inner diameter measurements for your chosen hose to make sure it is as effective as it should be.
