Due to the effects of reciprocating compressors, uncontrolled pressure pulsations and harmonic vibrations can propagate through the piping system, leading to significant challenges including mechanical fatigue and acoustic noise. These vibrations can adversely impact connected structures and equipment, potentially causing operational issues and reducing the overall efficiency of the system.
Mechartes specializes in addressing these challenges through comprehensive pulsation and vibration analysis, adhering to the guidelines of API 618. Our approach ensures that pressure pulsations and unbalanced shaking forces resulting from the operation of reciprocating compressors are managed effectively and comply with API 618 standards.
We conduct detailed pulsation analysis for suction, interstage, and discharge pipelines connected to reciprocating compressors, examining various operating scenarios. By comparing peak-to-peak pressure variations inside the pipeline against API 618 guidelines, we assess the vibration and harmonic loads along the pipeline’s length.
Our expertise extends to mechanical vibration analysis, where we ensure that the natural frequency of the pipelines does not coincide with the natural frequency of the compressor. We utilize Finite Element Analysis (FEA) to apply the harmonic loads obtained from our studies, evaluating stress concentrations and deflections within the pipeline. Based on this analysis, we provide targeted recommendations for design modifications, including the addition of pulsation dampeners, orifice plates, and pipe supports to mitigate vibrations and enhance system stability.
In addition to pulsation and vibration analysis, Mechartes performs pipe stress analysis to evaluate the loads acting on pipelines connected to compressors. We recommend appropriate pipe supports to ensure structural integrity and stability. Our services also include torsional studies to assess the impact of rotational forces on the piping system.
By implementing these design solutions, Mechartes helps maintain the reliability and efficiency of your compressor systems, ensuring they operate within safe and optimal parameters.
