Supply 1/4" to 2 1/2" stainless steel 304 continue spiral(helical) type corrugated flexible metal hose

Corrugated flexible metal hoses with their high temperature and resistance and easy bent structures are produced in two different versions (Annular&Spiral)depending on the corrugation types. Spiral corrugation: Spiral corrugated metal hose is also made from longitudinally welded tubing but with the corrugations formed in helix or spiral relative to the axis of the hose.
Size: DN6~DN50
Material: SS304,SS316L,SS321
Wall thickness:0.2~0.28mm

Discription
Corrugated flexible metal hoses with their high temperature and resistance and easy bent structures are produced in two different version(Annular &Spiral)depending on the corrugation types. You can choose one corrugated flexible metal hose which suits you.
Spiral corrugationLike annular corrugation, Spiral corrugation has a similar feature: Spiral corrugated metal hose is also made from longitudinally welded tubing but with the corrugations formed in helix or spiral relative to the axis of the hose. 

Flexibility of corrugated metal hoses depends on the profile and the distance between the corrugations as well as the wall thickness. Higher profiles with small distance between the corrugations provide more flexibility. In the same way, reducing the wall thickness also causes an increase in the flexibility, but in this case, the pressure resistance will be reduced. We can choose a suitable way to increase the spiral corrugated metal hoses’ flexibility according to the specific situation.

In order to increase the pressure resistance, flexible metal hoses are reinforced with single or multiple braiding. Braiding does not only prevent longitudinal expansion of the hose caused by interior pressure, but it can also absorb exterior tensile stress and provide protection of the exterior surface of the hose. Braiding can make spiral corrugated metal hoses be more durable too.
 
Corrugated metal hoses can be used in all applications where high flexibility and tightness are required, due to its functional and constructional properties. Another advantage of corrugated hoses is the absorption of vibrations. 
 

Forming Precess 
Stainless steel strip ---Automatic cutting ---Rolling TIG welding ---Corrugation forming
We can design spiral corrugated metal hoses according to the requirements of customers. Besides spiral corrugated metal hoses, we also have other spiral products, like spiral flexible metal hose, suspension system spiral vibration absorber and so on.

Ordering 
Corrugated metal hoses are normally manufactured in Standard Pitch. In general , each manufacture specifies a standard number of corrugation per meter based on their own specifications considering the acceptable flexibility. If you have specific requirements , pls let us know as follow:
---Normal diameter (Inner diameter)
---External diameter
---Length 
---Height of convolutions
---Pitch
---Wall thickness 
---Material selection
