Pulsation dampener - Pressure vessels - Quiri
Équipements sous pression destinés à amortir les surpressions cycliques ou intempestives générées par certains organes situés sur une ligne de fluide, ils jouent un rôle essentiel dans la pérennité d'une installation.
Quiri, spécialiste des échangeurs thermiques, vous propose un amortisseur de pulsations.

Technical specifications:

In a process of nitrogen and oxygen production, by multi-stage compression, our customer Burckhardt Compression asks us for pulsation dampers. Indeed, such an installation including different stages of compression, generates shock waves that affect the performance and efficiency as well as the mechanical strength of the entire installation, including the instrumentation and piping. At each pressure level, it is necessary to provide a device to dampen and reduce the amplitude of the waves propagating at the discharge of the compression stage. This equipment must be calculated taking into account permanent pulsations in a range of plus or minus 5% of the working pressures. Made of materials compatible with the fluids and the temperature and pressure conditions, in carbon steel, the devices must necessarily be built according to the CODAP and comply with the European Pressure Equipment Directive.
