Category: ISO Bellows

The metal hoses are circular corrugated all-metal hoses. The profiling on the corrugation determines
the elastic pliability and compressive resistance. The typical clip flange connections are welded onto the metal hoses. To eliminate temper colors and clean the weld seam, in a special vacuum annealing procedure the hoses are baked-pout at approx.. 1040 °C under forming gas. In this process, the metal hose is simultaneously soft-annealed and thus receives its extremely flexibility property. The flexibility makes smaller bending radii possible.

The metal spring bellows are corrugated metal bellows. The corrugated sections that run concentrically and parallel to one another give the metal spring bellows axial, angular and lateral mobility, whereby combinations of this are also possible. Metal spring bellows are not annealed.

The metal hose connections and metal spring bellows can be used as a mobile vacuum line. If they are used, ensure that the metal hoses can only execute bending movements in a lateral direction. Dynamic axial movements, i.e. buckling or pulling apart both in axial direction as well as torsional movement can only be executed by metal spring bellows. During evacuation of metal hoses as well as metal spring bellows, the air pressure applied from the outside results in a considerable force acting on the flanges, which causes compression. Only the spring power of the hose and bellows counteracts this. It may be necessary to compensate for the forces that develop.

Flexible bellows
Flexible stainless steel bellows are available in different standard lengths. Optionally we can offer these bellows in special lengths.

Flexible couplings
Maximum compression for flexible couplings is typically 20% of the convolution (flexible) length. Extension is typically 10%. Flexible couplings are available in 321 or 316L material.
