The metal hose must be checked before installation, and the problem will be eliminated in time; Figure 2 Metal hose L-type installation Figure 3 Metal hose Z-type installation download original map.During the lifting process, There is a measures to prevent metal hose damage;The short tube should be installed after the metal hose to compensate for the deviation of the hose neutral size;Try to use the metal hose set by the steel with mesh.

When the liquid is filled with liquid in the metal hose, axial thrust is generated. 4 Conclusions Combined with examples, analyzing various factors affecting the selection of metal hoses, most important is the determination of the length of the metal hose, too long and too short, will cause harm. In addition, the following factors should be considered: the nature of the medium, operating temperature, operating pressure, connection pipeline, the field category, connection method, displacement method, etc.

In summary, the storage tank export pipe metal hose is selected from PN2.The metal hose compensates for the axial displacement capability in the natural state.Metal hose selection metal hoses are widely used in the petrochemical industry, but there are some problems in the application, mainly due to the selection of hose and improper installation. This structure has good sealing performance, but the processing is difficult, and the sealing surface is easily injured.

At special occasions that need fast unloading, the well bolts can be opened, and the quick-unloaded flange is made. Widely used in petrochemical, steel metallurgy, rubber, machinery, electric power, etc. In order to solve the problems such as repeated demolition, brass fitting Suppliers installation and unyperforming in the actual engineering, the joint can also be designed to fit the fitting and the ball.
