Corrugated hoses are pressure and vacuum
tight. The permissible operating pressures for hoses with
small
dimensions reach **0 bar (with a *-fold
burst pressure safety factor). The pressure resistance of large
dimensions is
lower for technical reasons. Stainless steel
models have a temperature resistance of up to approx. **0
°C,
depending on the pressure load, and even
higher values are possible with special materials. In the low
temperature
range, stainless steel corrugated hoses can
be used down to ***0 °C.
Structure and function:
Corrugated hoses are used as economical,
flexible connecting elements that permit movement, thermal
expansion
and vibrations, and that can be used as
filling hoses. The starting material is a seamless or
longitudinally welded,
thin-walled tube into which corrugations are
introduced by mechanical or hydraulic means using special
tools.
Corrugated hoses are absolutely leak-tight
and are used to convey liquids or gases under pressure or as
vacuum
lines. They are also referred to as pressure
hoses. Their special design achieves both flexibility and
pressure
resistance.
Application areas of metal
hoses
With its ability to meet high demands for
conveying hot and cold substances, this modern technology has
the
following major areas of
application:
Electrical industry and mechanical
engineering: as a protective hose for electrical cables or light
conductors
As a suction, conveying and coolant hose,
e.g. when conveying and transporting liquid gas
Automotive industry: as an exhaust gas hose
that acts as a vibration decoupler in exhaust
systems
As a ventilation hose in technical building
equipment
Steel industry
Measuring and control
equipment
Metal expansion joint
(also called expansion
bellows) are compensating elements for thermal
expansion and relative movement in pipelines, containers and
machines. They consist of one or more metal bellows, connectors at
both ends, and tie rods that depend on the application. They are
differentiated according to the three basic types of movement:
axial, angular and lateral expansion joints.
In modern expansion joints, the metal
bellows are often produced with a so-called multi-ply design. To
increase both flexibility and stability, multiple thin plies of
metal are layered to form the bellow walls. There are two basic
design types: The multi-ply and the multi-walled bellows structure.
The multi-ply structure consists of a pressure-tight,
longitudinally welded outer and inner cylinder of stainless steel.
In between these cylinders is an open, spiral cylinder which forms
multiple plies depending on the design. The multi-walled structure
consists of several concentric, longitudinally welded cylinders.
Each cylinder forms a pressure-tight and closed
"wall".
Normally types are: axial / angular /
lateral expansion joint,
The main advantages of multi-walled
bellows:
Resistance to high and very high
pressures
Large movement absorption
Small dimensions
Small adjusting force
rates
Optimal compensation in a very small
space
Early leak indication (in case of damage)
via standard check hole
Complete burst resistance
Possibility of permanent leak monitoring in
critical media
Economical use of high-quality,
corrosion-resistant materials such as Inconel, Incoloy, Hastelloy,
titanium and Tantal
Insulation against structure-borne noise up
to *0 dB
