As a flexible pressure-resistant pipe fitting, the metal hose is installed in the liquid conveying system to compensate the mutual displacement of the connecting end of the pipe or machine and equipment, absorb the vibration energy, and can play the role of vibration reduction, noise reduction, etc., with good flexibility and light weight. , corrosion resistance, fatigue resistance, high temperature and low temperature advantages. As a professional metal hose manufacturer, I will introduce you to several elements in the process of selecting metal hoses.
Size
The nominal diameter of the metal hose is selected from the joint type (mainly flanged, threaded, quick joint) and the size of the metal hose, the length of the hose.
Pressure
According to the actual working pressure of the metal hose, check the nominal diameter and pressure gauge of the corrugated metal hose to determine whether to use the stainless steel mesh type metal hose.
Medium
The chemical properties of the medium conveyed in the metal hose determine the material of each part of the hose according to the corrosion resistance of the hose material.
Temperature
The operating temperature and range of the medium in the metal hose; the ambient temperature during operation of the hose. At high temperatures, the operating pressure temperature correction factor at the high temperature of the metal hose shall be determined to determine the pressure after the temperature correction to determine the correct pressure rating.
Status
According to the state of the hose when using, refer to the correct use of the metal hose and the installation method and the optimal length of the hose in the settlement compensation. Calculate the length of the hose in various motion states and the minimum bending times and minimum bending radius of the hose. The parameters are correctly selected and the hose length is correctly installed.
