Ducting Insights -- High Temp Hose Options

When you’re working with high temperatures, it is vital that you use types of duct hose that can stand up to the heat while remaining effective. Some industrial equipment reaches huge temperature spikes or creates scolding steam. Unless a high-temperature hose is used, the machinery will not stay in working order for long. Fortunately there are several ducting options designed specifically to deal with different high-heat conditions.

High-temperature duct hoses are available in a variety of materials, including silicone rubber, stainless steel, polyester and other plastics, fiberglass and aluminum. These different types have varying advantages, and offer flexibility depending on your needs. For instance, there are different grades of stainless steel hoses, and the one offering the highest heat resistance can stand temperatures up to an incredible 1650 degrees Fahrenheit. Silicone ducting on the other hand might top out at 500 degrees Fahrenheit. Other kinds of PVC ducting might be made to stand up to a 140-degree heat, which still falls under the high-temperature category.

These kinds of high-temperature hoses have a whole range of applications, from extraction hood hoses to chimney and furnace ducting. The specific function will dictate which high-temperature hose you need. Beyond the temperature resistance, varying materials will offer different advantages, such as strength, flexibility or lower cost.

One important distinction to make is that hoses with a resistance to high temperatures are not automatically flame resistant. This means that a flame can still damage the ducting material, even if it has major heat resistance qualities. If it is going to be in use around high temperatures and flammable materials, then flame-retardant ducting is the way to go.

Tips Before You Buy -- The Largest Hose Size Available

Not all ducting needs are the same, and sometimes you need a serious size of duct hose. Where a smaller ducting type will suffice in some situations, it will not do the job for every application. For instance, heavy-duty industrial ducting which needs to move air or materials in large quantities will need to be big enough to keep up with those demands. As such, it’s important to be aware of the size range of ducting hoses to make sure you are using the right equipment.

When you are talking about the size of ducting needed, there are two measurements to take into account – the length and the inner diameter (ID) measurements. The inner diameter refers to the straight-line difference across the end of a duct hose, not including the thickness of the hose walls. On, the maximum ID offered from stock is 24 inches. However, custom diameters measuring up to 60 inches are available for those in need of a major industrial-sized option. When it comes to length, most large-diameter ducting hoses come in lengths up to 25 feet or even 50 feet, depending on the specific product.

Even the largest ducting hoses, coming in at a custom 60-inch diameter, will retain the flexibility, durability and resistance of the ducting when it is in smaller forms. At their largest sizes, the duct hoses are perfect for transporting materials in large quantities and ventilating large spaces. A custom 25-foot continuous length hose would normally only be used in a large-scale industrial setting where a huge portion of ducting is needed without breaks or seams.

Tips Before You Buy -- When is Stainless a Good Hose Option

Stainless steel is just one of a host of different materials used to create various kinds of ducting hoses. Every material has slightly different properties which make them effective, and stainless steel is no exception.

So, when does stainless steel provide one of the best options for creating a ducting hose? First you need to be aware of its best and most valuable properties. As a ducting material, it is bright, clean and easy on the eye. It is also extremely strong and durable, allowing it to stand up to plenty of use and remain effective over time. Despite this strength, stainless steel is also a less pliable, unlike plastics and rubber hoses. This is an advantage, as it allows the material to be shaped to suit its application. Beyond this, it is resistant to corrosion and has a very high tolerance to heat. Some grades can even bear temperatures reaching 1650 degrees Fahrenheit.

As a result of this lengthy list of favorable qualities, stainless steel makes for a great hosing solution in a variety of different situations. Due to its attractive metallic look and resistance against stains, it can be used in locations where it might be left exposed, such as a hood in a commercial kitchen. Its resistance to corrosion from elements such as water and chemicals mean it can be used in environments involving moisture, while it can also thrive in industrial usage that involves extreme heat, such as chimney or steam ducting.

Another advantage of stainless steel is that it is semi-rigid. This means that it can be bent into shape and will then retain its form, making it perfect for any setting where the ducting hose needs to remain solid and in position. This reduces the need for connectors, since the hose will keep its shape when installed in complicated spaces. Community
