Introduction: The mesh cover of metal hose is made of metal wire and wire, which is the external surface protection layer of metal hose. The damage sample mainly includes the damage and disconnection of metal ribbon and the drum of mesh sleeve. In general, overload use of metal hose two or three days will promote the net set

Metal hose The net cover is made of metal wire and wire, which is the external surface protection layer of metal hose. The damage sample mainly includes the damage and disconnection of metal ribbon and the drum of net cover. Generally, overload use of metal hose three days or two will cause the damage of the net cover. In the use of metal hose, beyond the limit of the metal net cover, the net cover will grow a significant drum scenery.
1. The net cover is too loose
When the metal hose is on duty, the transverse load in the internal downward pressure initiated by the medium is basically borne by the corrugated pipe, and the covered net sleeve receives the vertical load. Because the net cover is mostly woven by equipment, when the net cover is too loose and the force is not enough, the side pressure of vertical load will lead to the phenomenon of net cover bulging.
2. The braiding angle is too large
If the braiding angle of the metal hose is too large, it will cause the net cover rate to be too large, the mesh cover will be loose, and the mesh sleeve and bellows will not meet closely. When the corrugated pipe is deformed, it is easy to grow bulge.
3. The bending radius is too small
In the actual installation process, it is due to the limited installation half space of the metal hose, and the length of the selected metal hose does not match the set air size. For example, the nominal size is DN 150, the rigid section distance of the sample is 100 mm, the vertical offset is 250 mm, and the installation small bending radius is 1800 mm. The length of the small sample is 7525 mm, but the actual length is 10000 mm As the outer part of the tube is bent, the deformation of the outer part of the tube will be limited, which will lead to the deformation of the sheath.
The above is the reason why the metal hose appears to bulge. If you want to master a lot of knowledge about metal hose, please continue to pay attention to our website.
