VIBRATION CONTROL
OF PIPING SYSTEMS
Pipework dampers are frequently used for the protection of piping systems and other components in power plants and industrial facilities. GERB pipework dampers are highly effective viscoelastic elements, well proven in numerous installations. Already in 1951 Viscodampers® were patented for
pipe applications.
Practical experience in power plants shows that the reliability and life expectancy of piping systems are largely determined by their dynamic characteristics and behavior. Dynamic loads are experienced during normal, continuous operation and during abnormal, potentially disastrous situations.
Advantages of Gerb damper
+ reduce vibrations in all degrees of freedom.
+ develop high damping forces in case of shock
loads, whereas slow motions are not hindered.
+ reduce operational vibrations by selectively increasing system damping.
+ react to vibrations immediately without delay or time-lag.
+ simple in design and handling und therefore cost-saving. There are no parts of wear and tear, and they are maintenancefree.
Example of installation
GERB pipework dampers can be installed below, above, or next to the pipe. Either the upper part of the damper (damper piston) or the lower part (damper housing) can be connected to the pipe. As the damper develops forces in all directions the load does not need to be in line with the damper axis. However, dampers always have to be transported and installed upright to prevent leakage of the viscous fluid.
