When mentioned nylon fabric duct hose, people may feel confused. What’s that? In fact, it’s the same with canvas duct hose, just different in name. Normally canvas is the tarpaulin, but many regard canvas duct hose as the nylon fabric duct hose.
In fact, the material of so called “canvas duct hose” is nylon fabric with high temperature coating. It has excellent mechanical and water proof properties. Temperature and ultraviolet makes it can work in the wild for long term. Besides, you don’t need any solvent and fuel during the installation. Thus it not only helps avoid the pollution to environment, but also eliminates the fire risk. Moreover, it has great stability and remains flexible in low temperature.
We can see the hose has so many advantages. However, not all the duct hoses on the market are high quality. Then what affect the quality of nylon fabric duct hose?
First is the raw material
We can see that the quality of raw material determines the quality of the hose. The main materials of nylon fabric is the fabric and steel wire. The authentic nylon hose resists oil and acid. However, some supplier use PVC fabric to instead nylon one. However, PVC fabric duct hose can’t be compared to nylon one. Because the properties are not that good. But the price is just 2/3 of nylon one. While the nylon fabric has different thicknesses. The thicker, the better the property will be, the lifespan will be long as well.
Besides fabric, the quality of steel wire is also matter. High quality nylon fabric duct hose absorbs elastic steel wire. Generally speaking, the hardness should be high enough. Otherwise the high temperature duct hose will be flattened only if there was a little pressure. While the good elasticity steel wire can return to the original shape even be flattened.
Technology is another important factor that affect the quality of nylon fabric duct hose. This hose absorb the heat seal method, Thus it’s easy to break during the seal with a little pressure. Besides, there will be air leakage if the seal is not tight. Once such problems appear, the whole hose will be the waste.
