Under what conditions can stainless steel metal hose not be used

The stainless steel metal hose has strong corrosion resistance, long service life and other characteristics, and is loved by many customers. However, some customers, relying on the characteristics of stainless steel metal hoses, do not pay attention when using them, and the stainless steel metal hoses will be scrapped before reaching the original service life.


1： The stainless steel metal hose does not withstand enough pressure to burst because the pressure and temperature of the escorting medium are too high, and the corrugated pipe does not withstand enough pressure to burst. This kind of damage is caused by design and type selection error, so the selection should be stopped strictly according to the hose design and type selection specification, and the parameters of stainless steel metal hose and net sleeve should be affirmed


2： Weld cracking. The flexible corrugated pipe section in stainless steel metal hose ly adopts longitudinal seam welded pipe. Due to the quality defects of longitudinal seam welding, the pipe strength is not enough to cause cracking and damage at the weld. This damage belongs to the quality problem of the longitudinal weld of the bellows, so the control of the weld quality should be strengthened.


3： The stainless steel metal hose and steel wire mesh sleeve pull off. Due to the reason of welding quality, the corrugated pipe, ring and wire mesh sleeve will form a part of the steel wire in the process of trinity welding (over burning or last welding).


4： The wire mesh is pulled off. During the installation process of stainless steel metal hose, due to improper installation or high pressure, the stainless steel metal hose will be stretched and twisted. When the stress generated by stretching or twisting exceeds the ultimate strength of the hose wire mesh sleeve, the mesh sleeve at the welding part of the trinity of the hose or the mesh sleeve at other parts will be pulled off, thus causing the external drum of the corrugated tube to be stretched and damaged, causing the leakage of the medium. Therefore, the design and model selection should be accurate, The device is correct.


5： Fatigue failure Under the dynamic working condition, the stainless steel metal hose is often damaged by fatigue cracks under the cyclic load. Such destruction is normal failure. In order to prolong the service life, it is necessary to ensure that the stainless steel metal hose is correctly designed and selected, the device is accurate, and no additional stress such as twisting occurs to the stainless steel metal hose.


6： The welding quality defect of stainless steel metal hose connector (internal connection part) causes leakage failure of stainless steel metal hose. When the stainless steel metal hose body is welded with the hose connector, it will produce welding defects when the operation is improper, and these defects are difficult to be found during the pressure test inspection. When the stainless steel metal hose is connected to the medium pipeline, it will crack or break at the defect due to fatigue and other reasons after long-term use, and finally form the medium leakage of the escort pipeline.
