A pulsation study by KÖTTER Consulting Engineers goes far beyond examining your pipes. Complex compressor systems are subject to comprehensive influences that must be viewed just as comprehensively.
We keep an eye on all excitation and amplification mechanisms. We watch out for overflowing line branches and valves. We consider vortex shedding and repercussions on the piping system. We always react in time, e.g. using optimised pulsation dampeners or by adjusting pipe routing. This way, you will be able to look at your pipes with satisfaction throughout the planning stage and beyond. You’ll always know just what to do.
- Studies in accordance with API 618 (reciprocating compressors), API 674 (reciprocating pumps)
- Reliable results by calculating gas and fluid-induced vibration over time (adaptive method, non-linearity, etc.)
- Quick damper checks and checks of the power unit loading
- Investigations on valve dynamics
- Structural dynamics calculations (over time) for the mechanical vibration and dynamic stresses on components (mechanical response) to be expected in the piping system
- Acoustic simulation of the system after definition of the relevant scope in agreement with the customer
- Optimisation of the support concept for piping system and vessels
- Static pipe stress analysis and reconciliation of the results from the structural dynamic calculations
- Consultation in detail planning and implementation, e.g. for flow metering systems
The benchmark for conversion: A combination of calculation and measurement.
Most plants are modified or adjusted to new uses during their service lives. In a compressor system, for example, the composition of the gas flowing through may change or parts of the system may be modified. Both will influence the piping acoustics and therefore overall operation.
We do not stop at performing a pulsation study in advance to take this into consideration. We can also include all essential aspects in our analyses and recommendations based on additional measurements conducted on the existing system to support smooth operation in the long term.
