The inner wall types of rubber industrial hoses
In the petrol and chemical industry, metal hose places a great part. Because it resists heat, chemical, oil and high temp. Besides, it is strong enough to prevent impact. But there are also some problems in use.
Problems for metal hose
The main reason is improper select and install of the hose. Too long hose will cause system unstable and increase fluid force. Besides, it causes mechanical damage and vibration. But if the hose is too short, it can’t reduce the vibration and eliminate the noise. Therefore, first focus on the length of the metal hose. In addition, focus on the nature of the medium, work temp, work pressure and nominal size. In the same time, consider the site type, connect method and other factors.
Correctly install metal hose is an important part to make it perform well
Usually the metal hose is behind the root valve of the tank inlet and outlet. There is also a valve behind the metal hose. So that the tank body and the pipeline directly form a soft connection. While this is simple to replace the flexible metal pipe. In the natural state, the axial displace ability of the metal hose is limited. When the length is equal to the natural length, it must not be able to bear strong axial tension. Then it will cause fracture and result in leakage. Therefore, the length of the metal hose should be smaller than the natural length. Then it can ensure a certain degree of freedom.
