Aluminum foil corrugated pipe is widely used in petrochemical, instrumentation, aerospace, chemical, electric power, water, metallurgy and other industries, because it can compensate the thermal deformation of pipelines, absorb shock and absorb the settlement deformation of pipelines. It has the characteristics of low cost, reliable performance and high heat transfer efficiency. In use, we need to pay attention to the following details.

1. State, the state of aluminum foil corrugated pipe when in use. Refer to the correct use and installation method of metal hose, Z optimal length of hose during settlement compensation, length calculation of various motion states of hose, and factors such as Z small bending times and Z small bending radius of hose, etc., select the hose length correctly and install it correctly.。

2. Size, nominal diameter of metal bellows hose, joint type (mainly flange connection, threaded connection and quick joint connection), size and length of metal bellows hose.

3. Temperature, the working temperature and range of the medium in the aluminum foil bellows hose, and the ambient temperature when the metal bellows hose works. At high temperature, the pressure after temperature correction shall be determined according to the temperature correction coefficient of the working pressure of the metal bellows at high temperature, so as to determine the correct pressure grade.
