The Benefits of a Clear PVC Hose

Some customers require ducting which has specialist capabilities, such as super heat resistance or ultra tough walls. But most people need a versatile all-rounder which provides quality ducting in a wide range of settings at an affordable price. When you are looking for such ducting, a general purpose clear PVC hose is a standout choice. These hoses have a series of top qualities which set them apart as some of the best and most versatile ducting hoses available.

The benefits of a clear PVC hose start in the name with the coloring of the hose. A clear PVC hose will have transparent walls which you can see through. The see-through nature of the walls is an extremely important feature of the duct’s effectiveness. Having a clear hose is helpful in viewing what is going on inside the hose, which is especially vital when something goes wrong. For instance, if pressure is lost inside the ducting, it may be the result of a blockage. Ordinarily you might be held up by a lengthy diagnosis period. But with a clear PVC hose, you will easily be able to easily locate the source of the blockage, or any other issue inside the hose. This is a much harder process with solid-color hoses. The quicker you can locate a problem, the quicker you can fix it. This efficiency is just one of the advantages provided by a clear PVC hose.

The benefits of a clear PVC hose are not restricted to its aesthetics. Made from durable PVC plastic, these hoses are extremely flexible and can be contorted into tight shapes and spaces to meet specific project demands. They are also highly compressible, and the PVC material has a reasonable level of chemical resistance. Just as importantly, clear PVC hose products are extremely cost effective when compared to other options on the market.

Large Diameter Duct – How Big Can You Go with Ducting Hoses?

When it comes to choosing the right ducting hose you have plenty of variables to consider. One of the most important is the inner diameter – the size of the opening at each end of the duct. Some applications require a large diameter pipe for large-scale usage. An example of this is in industrial applications which might require the movement of air, fumes or material in high quantities. In such scenarios only, a large diameter pipe would be needed in order to keep up with the desired movement demands.

When buying a ducting hose there are two relevant measurements – the length and the inner diameter. The length is self-explanatory, but it is the inner diameter which is most important when sizing up a large diameter pipe product. The inner diameter refers to a duct’s end opening, and is taken by measuring across the opening without including the thickness of the hose walls. A large diameter pipe will have a higher inner diameter measurement, giving it a higher capacity for air and material movement.

The maximum inner diameter offered as standard on is 24-inches. A 24-inch inner diameter represents a large diameter pipe, but some applications might require an even larger option. For this reason, custom diameters are also available, ranging up to 60-inches in diameter. These larger sizes make sure even the largest scale needs are catered for. A large diameter pipe of 24-inches inner diameter would have to be specially ordered. These could be used to vent industrial machinery fumes, ventilate large spaces or transport high material quantities. Even at these significant sizes, a ducting hose will retain the qualities of flexibility and resistance that it would have in a smaller size, dependent on the materials that it is made from.

Steel Ducts – The Ultimate High-Temperature Ducting

When you buy a ducting hose, there are a few considerations that you need to weigh up to make sure you get the most effective hose for your application. One of those considerations is the temperature that a hose can handle – a vital point, especially for those dealing with extreme temperature applications. You need to make sure that whatever duct you get will not fail or fall apart when faced with serious temperatures. For the most intensive high-temperature environments, steel ducts are the way to go.

The material of a ducting hose is one of the main factors in how much heat it can handle. For instance, an aluminum hose will be far more heat-resistant than a PVC hose. However, a stainless steel duct will handle high temperatures better than almost every other material. Not many stainless steel hose variants are available because they are more of a specialist item with a greater degree of resistance than is required in most situations. A standard stainless steel duct will be able to stand up to regular temperatures ranging from -400 degrees to 800 degrees Fahrenheit. This is a significantly higher level of temperature resistance than the vast majority of hoses on the market.

Silicone and fiberglass are both used in hoses that have extremely high temperature resistance points, even rivalling the standard stainless steel hoses. However, when stainless steel is reinforced with a tiny 0.5% portion of titanium, it creates an unparalleled form of heat-resistant hosing. A stainless steel duct with titanium will be able to take temperatures up to an incredible 1650 degrees Fahrenheit. This form of stainless steel duct is for you if you need an ultra-resistant hose for the highest stress industrial applications, from furnaces and chimneys to steam ducting.
