Metal hose selection includes the connector type (mainly flange connection, threaded connection, and quick coupling connection), as well as the size and length of the metal hose. The specific five factors are as follows:
1. Size – The nominal diameter of the hose determines the selection of connector type (mainly flange connection, threaded connection, and quick coupling connection), as well as the metal hose dimensions and length.
2. Pressure – The actual working pressure of the hose must be considered. Then, consult the nominal diameter and pressure rating chart of the corrugated metal hose to decide whether a stainless steel braided metal hose is required.
3. Medium – Based on the chemical properties of the medium being conveyed through the hose, the material of each hose component is determined according to the corrosion resistance of the hose materials.
4. Temperature – The working temperature and range of the medium inside the hose, as well as the ambient temperature during hose operation.
5. Movement Conditions – Factors such as length calculation under various movement states, number of bending cycles, and bending radius must be considered. Properly determine the hose length based on these parameters and install it correctly.
