In addition, the following factors should be considered comprehensively: the nature of the medium, operating temperature, operating pressure, the nominal diameter of the connecting pipe, the site category, the connection method, the displacement method, etc. To Metal hose installation type The correct installation of the metal hose is an important link to ensure its full performance.

The metal hose is usually installed after the valve at the root of the tank inlet and outlet pipe, and there is also a valve after the metal hose, which makes the storage tank and the pipeline directly form a soft connection, which is convenient for the maintenance and replacement of the metal hose. The metal hose has a limited ability to compensate for the axial displacement in the natural state. When the installation length is equal to the natural length, it will inevitably not be able to withstand strong axial tension and break, which will lead to pipeline leakage.

Therefore, the installation length of the metal hose should be less than the natural length to ensure a certain degree of freedom. To Schematic diagram of metal hose installation Since the metal hose mainly absorbs the lateral and axial displacement generated by the system, in addition to ensuring the freedom of the metal hose during installation, it can also be absorbed by the arrangement of the pipes.

There are two common piping methods, L-shaped (see Figure 2) pipe fittings And Z-type installation (see Figure 3). L-shaped installation is more common, the overall layout is neat and beautiful, reducing the length of the pipeline, reducing fluid resistance, but the axial stress generated by the pipeline will act on the metal hose and the nozzle of the storage tank, which shortens the use of hoses and valves Life expectancy will also damage the nozzle and cause oil leakage.
