1.Metal flexible hose 

 metal flexible hose is a kind of high-quality flexible pipe in modern industry pipeline.As a result of austenitic stainless steel manufacture ,the hose has good flexibility,fatigue resistence,hot and low temperature resistance,corrosion resistance,and many other features.

 

The elasticity property of corrugated pipe outline causes it very easy to absorb each kind of movement distortion and the cyclic load ,especially has the ability of compensating the big displacement in the piping system.The hose's life is much higher in relative to many others.Therefore it also has the high mixed economic efficiency.

 

The flexible hose is suitable for the pipe which need fully flexible and tube which prevent vibration premises,it is also appliacable to steam,gas,air,oil,chemical and pharmaceutical,etc.
