Metal hose damage part of the reason for the introduction.

Metal hose is due to the manufacture of the primary parts of the hose material is the choice of austenitic stainless steel, and then ensure the hose temperature resistance and corrosion resistance, the use of the hose according to the erosive nature of the medium through the pipeline to select the appropriate stainless steel trademark, so as to ensure the corrosion resistance of metal hose. Widely used in machinery, chemical industry, petroleum, metallurgy, food and other occupations. Due to the extensive use of metal hose, and therefore about its use of life has come to be paid more and more attention to, so what are the reasons for the formation of metal hose damage?
 
Wire outer network pull off, can not accept the pressure, making the early end of the life of the metal hose. Because of the internal bellows, both ends receive and outside the wire mesh needs to be welded together as a whole trinity, to ensure the normal use of metal hose. If the welders to carry out the whole welding a little careless, will be flooded with trinity welding failed, once the device for operation, it will make the outer network pull off, can not damping. In order to prevent this phenomenon, the product factory to carry out gas-tight water pressure test, qualified before the factory use.
 
The internal bellows seam has open weld appearance, which will also make the metal hose damage reason. This is due to carelessness and carelessness of the welder's skills and the formation of damage, due to the welding seam is not solid, not fine, in the hose activity medium under the effect of operating pressure, the welding seam taut open, making the metal hose leaking appearance.
 
In summary, the metal hose in the delivery and installation process may also cause damage, therefore, this point warns us, in the delivery process must be packaged early, the installation process, do not splash welding slag to the bellows or wire mesh above.
