The Vibration Absorber ‘Magic Tube’—Different Applications on Site

In several industries, increased vibrations often occur at pumps, compressors or turbines and at the connected piping systems. These vibrations can have different causes. Different measures can be used to decrease this vibration level. In many cases, additional supports are used to tighten the piping. But in some cases, it is not possible or very expensive and inconvenient to install additional piping supports or damping devices. Another very effective measure is the use of vibration absorbers [Lenz J (2008) Three-dimensional vibration absorber to eliminate high vibrations in pipelines. In: Gas machinery conference. Albuquerque, New Mexico]. Especially vibration absorbers with an implemented damping characteristic enable a significant optimization of the vibration characteristic in a broad frequency range. In this paper, the vibration absorber Magic Tube is presented. The vibration absorber is adjustable on site in a wide frequency range with different mass configurations. The design is introduced, and a case study shows the vibration reduction effect in the field.
