Bellow types
Bellow is an internal part of a metal hose that ensures flexibility exposed to leak tests while production process.

Used for the majority of machine control systems.
Standard bellow is used in most cases. Its bending radius and strenghtare fit for any common purpose of a metal hose used.

In less critical areas, with or without low pressure
One can use a lightweight bellow in less critical areas (for example, those with low operating pressure or when a bellow is used as protective device or to shield wiring, for instance, in an unpressurized system).

High flexibility

If necessary, increase the flexibility of the standard sleeve
In cases where the bending radius is not sufficient, a bellows with increased flexibility is used,
achieved by changing the pitch of the bellows, or by compressing it. The strength characteristics are
somewhat reduced at the same time.

When selecting a sleeve, it is necessary to take into account the parameter of the operating pressure of the system, if insufficient
according to the characteristics of a standard bellows for this indicator, you can apply a double (or even
triple) outer braid, or use a high-strength bellows (reinforced).
Braid types
Braid is an external part of a bellow that consists of stainless-steel wire strands over 0.3 mm thick, depending on diameter.
Stainless-steel metal hoses are braided with cutting-edge braiding machines. Braid operates not only as the shielding that protects the internal flexible bellow of the metal hose from mechanical damage and aggressive environment.
A high-pressure metal hose braid is a crucial component that has a direct effect on technical characteristics of the end item, especially its ability withstand the required operating pressure: when a metal hose with a single braid is not strong enough (one layer of wire strands), one puts the second or even the third one.
0 - unbraided
1 - single braid
2 - double braid
3 - triple braid
