Over the past 30 years the plant engineering sector has faced a constant increase of the vibration level at piping systems for multiple reasons. One important factor is the increased requirements on economical operation and productivity. The quantity of steel used with piping systems is reduced, due to higher quality of material and higher utilization factors. Usually, piping systems are designed against static load cases only. During operation, however, dynamic loads occur. These loads may lead to excessive vibrations that need to be reduced.
VICODA has developed an innovative solution to reduce vibrations in a simple way: TMD.Pipe.
TMD.Pipe (TMD stands for Tuned Mass Damper) is a passive damper for the reduction of vibrations in piping systems and is composed of a mass, springs and dampers.
Functional principle: The TMD tuned to the resonance of the piping system increases the damping significantly, thus reducing the resonant amplitudes.
TMD.Pipe is based on an innovative design allowing for the use of only one product to solve a wide range of vibration problems in a wide variety of facilities and piping systems. Characteristics:
Due to the eddy-current dampers applied TMD.Pipe is far more efficient than vibration absorbers applying conventional dampers:
