PU vacuum hose is a branch of industrial vacuum hose. It widely serves in many apps because of the great properties. But the use of any hose has a specific range. PU vacuum hose generally serves in industrial for dust collect, wood work, ventilation without corrosive oil. While in the daily use, you should focus on these
Pressure and temperature
The PU suction pipe needs to maintain a long service life. Besides, you must use it under the rated working pressure and temp. Because the thickness of the pipe wall and the temp of use are always limited.
Temp range: about -40°C to +120°C, up to 150°C for a short period of time. As the temp rises, the working pressure of the PU hose should decrease accordingly. While if it exceeds the limit, the hose may burst.
What to pay attention to when vacuum with water drops
When the pumped PU vacuum hose contains liquid, focus on the temp. Because if the temp of the liquid is too high or the liquid contains corrosives, it may cause the hose to rupture.
The influence of external factors
The PU vacuum hose is used in a specific space. When the temp of the working condition is too high, it may cause the hose to crack.
Consumption in storage
The PU vacuum hose resist hydrolysis and anti-aging. But it is not static. When the hose in the warehouse for a long time, the hose will change, which may lead to breakage.
