The large-diameter metal hose is made of stainless steel SUS304 or SUS301. It is used as a protective tube for wires, cables, optical fibers, automation instrument signal lines and instrument wire and cable protection tubes. The outer diameter can be from 3mm to 150mm. The small-diameter stainless steel metal hose is Protection of precision electronic equipment and sensor circuits, protection of precision optical ruler sensing circuits, and protection of industrial sensor circuits. It has excellent softness, corrosion resistance, high temperature resistance, wear resistance and tensile strength.

1. Dimensions: nominal diameter of hose, selected joint type (mainly flange connection, threaded connection, quick connector connection) and size of metal hose, hose length.

2. Pressure: According to the actual working pressure of the hose, check the nominal diameter and pressure gauge of the corrugated metal hose to decide whether to use a stainless steel mesh type metal hose.

3. Medium The chemical properties of the medium transported in the hose determine the material of each part of the hose according to the corrosion resistance of the hose material.

4. Temperature: the working temperature and range of the medium in the hose; the ambient temperature when the hose is working. At high temperatures, the temperature-corrected pressure must be determined according to the temperature correction coefficient of the metal hose's working pressure at high temperatures to determine the correct pressure level.

5. Status According to the status of the hose when used, refer to the correct use and installation method of the metal hose and the length of the hose during settlement compensation. Calculate the length of the hose in various motion states and factors such as the minimum number of bends and small bending radius of the hose. Select the hose length correctly and install it correctly.
