The axial displacement of the pipe system can be absorbed by itself

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 cause pipeline leakage. Therefore, the installation length of the metal hose should be less than the natural length to ensure a certain degree of freedom. The installation diagram of the metal hose is shown in Figure 1.

In Figure 1, L is the length of the metal hose and Smin is the minimum installation displacement. Smin depends on the size, structure, pipe diameter, compensation amount and length of the metal hose, and is estimated by the common formula (3.1.1). 

Figure 1 Schematic diagram of metal hose installation In the formula, the coefficient a is selected from Table 5. Table 5 Selection of coefficient a 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 pipeline. 

There are two common piping methods, L-type (see Figure 2) And Z-type installation (see Figure 3). L-shaped push on fittings Manufacturers 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 span will also damage the nozzle and cause oil leakage. 

Although the Z-type installation increases the length of the pipe and the number of elbows, the axial displacement of the pipe system can be absorbed by itself, reducing the axial stress on the metal hose and nozzle, extending the service life, and also conducive to the stability of the pipe system .
