Here is a list of materials industrial ducting are made out of. Below gives a brief description of each material and why each is selected for use in flexible hoses. The common thread across all of the below materials is that they are flexible enough to be the material make-up for flexible hoses.
Aluminum Hose – Aluminum is one of the most widely used metals in the world. Combining physical durability in a lighter weight form, aluminum is very popular for use as a flexible hose. Compared to other metal compounds used to make flexible hoses, aluminum is the more cost-efficient option. An aluminum hose is best used for high temperature air movement applications. Aluminum is a good material for resisting the corrosive effects of hot temperatures reaching up to 400° F. Aluminum flex hoses also maintain their shape when flexed, which sets them apart from most plastic ducting.
Fabric Hose – Hoses made from fabric materials are very popular in the market because they are lightweight, mobile, and budget friendly. If you need a flexible hose for air movement, a fabric hose is a smart option. The fabric material used to make flexible hoses is usually coated in plastic or rubber compounds, the most prominent examples being neoprene and PVC. This coating gives the hoses an improved level of physical durability and even protection against harsh chemicals and elevated temperatures. Since fabric is so lightweight, it is easier to compress fabric hoses down to smaller sizes, meaning that fabric hoses are easy to transport.
Fiberglass Hose – A flexible hose made from fiberglass is the ideal solution for high temperature air and fume applications. Fiberglass is composed of a plastic base that is woven through with a glass fiber. When used as the material for flexible hoses, the fiberglass body is often coated with an elastomeric compound such as silicone or neoprene. People should get a fiberglass hose when they need a flexible hose for transferring harsh fumes at high temperatures. A fiberglass hose is not the type of ducting that can tolerate continuous flexing. It can be bent in some directions, but not on a constant basis.
