ZHW cooper bellows have been designed to control vibration, reduce noise, relieve stress, prevent system shock and compensate for misalignment and movement. Use of braided metal connectors for applications such as pumps, compressors, and other mechanical equipment will enhance the overall operation of the system.
ZHW cooper bellows are used in lots of applications, where it concerns safety, health, environment, durability and lifetime. Bellows are made from stainless steel strip which is first welded to a thin walled tube and formed to a bellow afterwards.
Bellows are normally unbraided and capable to absorb axial, lateral and angular movements while being under low or higher pressures and temperatures. Due to the construction techniques involved the bellows are relative light compared to equivalent non-metallic bellow alternatives in the market.
Description
ZHW copper bellows has a superior tensile strength and electrical conductivity when compared to the other bellows materials. It can be soldered or brazed. Age hardened beryllium copper is often incorporated into a bellows assembly, which can then be heat treated for maximum dimensional stability. ZHW copper bellows are often favored in applications requiring a small package size and demanding lifecycle requirements. Among these applications are aerospace systems and instrumentation.
- Absorbs and isolates troublesome pipeline vibrations
- Smooths out force-pump system pulsations
- Tranquillize jittering compressor pipelines
- Also absorbs pipeline expansion, compensates for misalignment, eliminates piping stresses.
- Ends costly failure and downtime caused by pipeline vibration transmissions
- Customized to solve your vibration problem
