Precautions to choose a high quality PU hose
In the last piece, we learned2 factors to choose high temp duct hose. They are pressure and temp. While this time, let’s learn the other 4 factors.
Corrosion from the medium
It refers to the medium and its nature that transferred by the high temp duct hose. Medias will directly determine the material of the hose. When need to transfer corrosive materials, you should know what’s the chemical is. Because chemicals have different corrosion grade. In another hand, there are many materials for such duct hose.

Inner diameter
We generally refer to the inner diameter of the hose. Because the hose is usually connects with the hard pipe. So that the size should be proper. Larger or smaller size will cause the bad connection. It can produce high temp resistant hoses with an inner diameter of 40-900 mm.
Bend radius
Because of the different work conditions, the install positions are not the same. Thus the demand to bend radius is not uniform. So you have to choose a more flexible hose. So that it can fit all the conditions.
Vibration and distortion
During the use, there will be vibrator and distortion. So the length of your hose should be longer than the real demand. Because if the hose is to tight, the vibrator may break it. In another hand, it may cause the hose release and fall.
