High Temperature resistant fire sleeve widely serves in petrochemical industry
Correctly install steel hose pipe is an important part. Because it can ensure that the metal hose can fully perform its property. The metal hose is usually after the root valve of the pipeline of the tank. There is also a valve after the metal hose. So that the storage tank and the pipeline directly form a soft connection. Then this makes the ss flexible hose easy to check and replace. The metal hose compensates for limited axial displacement capacity under the natural state. When the install length is equal to the natural length, it is not able to withstand strong axial stretching and cause breaks. Then it will cause leakage. Therefore, the install length of the metal hose should be less than the natural length. Then this can ensure a certain degree of freedom.
Two steel hose pipe installation types
The metal pipe is mainly to absorb the displacement. In addition to ensuring the freedom of the metal hose, it can also do this by the layout of the pipeline. There are two common methods, L type and Z type. L type is more common. The overall layout is neat and beautiful. Besides, it reduces the length of the pipeline and fluid resistance. But the stress that the pipe produce will affect the metal pipe. Then it will reduce the service life of flexible hose and valve. Besides, it will cause leakage.
Z type increases the length of the pipeline and the number of elbows. But the axial displacement of the tube can be absorbed by itself. Then it reduces the axial stress of the metal hose and the pipe mouth. Then this and extends the service life. It is also conducive to the stability of the tube system.
In a word, if you concern about the safety and service life, Z type is much better. Thus Z type is the first choice if the plat position allows.
