Product details
Most of our metal expansion bellows have been in use for decades. They ensure trouble-free operation. Example applications include mechanical engineering, industrial equipment construction and pipeline construction. In the chemicals industry, plant engineering, gas and water supply, building services engineering and exhaust systems engineering, etc.

Advantages:
Compensate motion/expansion
Reduce tension
Damp vibration and noise transmissions
Compensate ground and foundation settling
Compensate inaccurate assembly
Wide Size and Service Range
The 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 20 dB
