Metal bellows - Import export

The term metal bellows refers to a structure that is composed of one or more stainless steel sleeves fitted into one another and is rendered elastic by the introduction of parallel corrugations. Metal bellows can be arranged to complete combinations of metal bellows (expansion joints). Thus, every specific requirement can be met.

Thermostatic valves - i.e. the temperature controls on the heating system - are found in just about every home. In the head of a thermostatic valve there is a metal bellows, a corrugated tube that expands according to the room air temperature. For these metal bellows, the manufacturer needed deep-drawn, very long and thin-walled sleeves. The challenge: the sleeves must be matched to the customer's downstream process under very tight tolerance specifications. Why? Because the sleeves cannot be further processed if the geometries vary. Absolute precision is therefore required. We can offer absolute precision. The customer commissioned us with the production of the sleeves. On the one hand, because we fulfil the special deep-drawing requirements. On the other hand, because we can offer an associated, targeted heat treatment for material stress relief in-house.

Universal expansion joints absorb axial, lateral and angular movement simultaneously. Installation is primarily in the low pressure area. Using a guide tube protects the metal bellows from abrasive media or flow-induced oscillations. The reaction forces caused by the internal pressure must be absorbed by sufficiently dimensioned anchor points.

Axial expansion joints compensate assembly tolerances and thermal longitudinal expansion in the direction of the tube axis. Depending on the design, they can be impinged with pressure internally and externally. Using a guide sleeve protects the metal bellows from abrasive media or flow-induced oscillations. The reaction forces caused by the internal pressure must be absorbed by sufficiently dimensioned anchor points.
