INDUSTRIAL VACUUM HOSE
There are many types of industrial vacuum hose. I will attempt to explain the types of hoses and briefly discuss some of their applications. First let me list the main types of vacuum hoses.
Nylon or Glass Reinforced
This seems pretty basic and it is. The reason is there are a large number of subcategories in each of these basic hose types. This will be covered in another section later.
Plastic vacuum hose generally falls into two types of hose. The hose types are PVC and polyethylene. These hoses are hard to the touch. The PVC hoses can be soft or hard depending on the chemical composition. However, the polyethylene hoses are generally categorized as crush resistant. Both types of these hoses are corrugated on the outside. The inside of the vacuum hoses can vary depending on the manufacturer. The insides of the hoses can range from corrugated, semi smooth or smooth. Smooth hoses on the inside are more desirable since they offer the lowest drag coefficient. Plastic vacuum hoses can be modified in a variety of ways to suit the application. For instance, carbon can be added to make the hose dissipate static electricity. Wires and fabrics can be added to the vacuum hose for support.
Next we have rubber vacuum hose. It is a desirable hose but generally comes with a price tag. It is manufactured with a variety different compounds to offer chemical resistance against chemicals such as sulfuric acid and oil resistance. Rubber vacuum hose is very abrasion resistant. It is going to be the choice when it comes to sand and highly abrasive materials. That is if you do not want to keep replacing the hose. Other benefits to rubber vacuum hose are its weight. It can be manufactured in large diameters with thin walls. This allows the hose to be flexible, abrasion resistance and light weight. Types include EPDM, SBR, EPDM, Neoprene, NBR, Nitrile vacuum hoses and blends. Rubber vacuum hose needs to be corrugated and generally will always have a smooth interior. There is one thing to remember when it comes to rubber hose. You get what you pay for.
Vinyl is the next hose to discuss. It is lighter than rubber. Vinyl hose offers good chemical resistance and can be made smooth. Vinyl vacuum hose is flexible. Do not put this hose in the same category as PVC. This hose can be made to be completely grounded and foodgrade. Vinyl hsoe can also handle a wide temperature range that plastic hoses cannot withstand.
Urethane vacuum hose is known for its abrasion resistance, light weight, and wire reinforcement. Urethane itself is resistant to static charge. However, due to the pitfalls of the processes that manufacture the hose, the hose isnít completely anti static. However, it can be grounded easily and offers great static dissipating qualities. There are anti static compounds available in urethane. Generally speaking, urethane hose is a little pricey. The most common vacuum hose in urethane is 30 thousands of an inch. The cons to the hose is it can be punctured and is not well suited for some harsh plant environments.
Last but not least is glass reinforced type hoses. Fabric vacuum hoses are economical and can be used in a wide variety of applications. The hoses are extremely flexible and can be made in a wide variety of colors. Generally these industrial vacuum hoses will consist of pvc as the primary material and a glass or yarn filament. These hose can be wire reinforced and connected end to end for grounding purposes. The hose can be fitted with hose cuffs. It can hold up reasonably well. It is suitable when a lot of damage is occurring to hoses and when costs need to be controlled. We recommend this industrial vacuum hose when dust loading is very light, the material is not extremely abrasive and the duty is intermittent.
