At Mechartes, our API 618 Pulsation and Vibration Analysis services are crucial for ensuring the reliability and performance of reciprocating compressors and their associated systems. With 20 years of experience in the process industry, we leverage our extensive expertise and advanced technology to address pulsation and vibration issues effectively, which are vital for maintaining operational efficiency and preventing equipment damage. Our approach involves dynamic simulation techniques to model and analyze pressure pulsations within reciprocating compressors and piping systems. Based on this analysis, we design and recommend control measures such as pulsation dampeners and buffers to minimize pulsation effects and stabilize system pressure, ensuring compliance with API 618 standards and other relevant industry codes.

We specialize in comprehensive pulsation and vibration analysis, including detailed assessments of suction, interstage, and discharge pipelines connected to reciprocating compressors. By comparing peak-to-peak pressure variations against API 618 guidelines, we evaluate vibration and harmonic loads along the pipeline’s length. Our expertise also extends to mechanical vibration analysis, using Finite Element Analysis (FEA) to assess stress concentrations and deflections within pipelines under harmonic loads. We provide targeted recommendations for design modifications, such as the addition of pulsation dampeners, orifice plates, and pipe supports, to mitigate vibrations and enhance system stability.Additionally, our services include pipe stress analysis and torsional studies to ensure the structural integrity and stability of pipelines connected to compressors. By implementing these solutions, Mechartes helps maintain the reliability and efficiency of compressor systems, operating within safe and optimal parameters. Our commitment to excellence and adherence to industry standards ensures that we deliver high-quality, effective solutions tailored to meet the specific needs of each project.

API 674 and API 675 Pulsation and Vibration Analysis

At Mechartes, our API 674 and API 675 Pulsation and Vibration Analysis services are crucial for optimizing the performance and reliability of positive displacement pumps and their associated systems. Focused on the pulsation and vibration challenges specific to reciprocating pumps, our expertise ensures these issues are effectively managed to uphold system integrity and efficiency. Using advanced dynamic simulation techniques, we model and analyze pressure pulsations within pump systems, evaluating their impact on pipelines, vessels, and equipment. Based on this analysis, we design and recommend control measures, such as pulsation dampeners, accumulators, and pressure relief valves, to minimize pulsation effects and stabilize system pressure, ensuring compliance with API 674 and other industry standards. Reciprocating pumps can cause uncontrolled pressure pulsations and harmonic vibrations that propagate through piping systems, exciting connected structures and equipment. These vibrations can lead to mechanical fatigue, acoustic noise, and high-pressure pulsations, potentially causing cavitation, excessive vibrations, and failures. Additionally, high-frequency fluid-borne noise from flow perturbations, such as those around elbows, valves, or changes in pipe cross-sections, can exacerbate these issues. To address these challenges, Mechartes follows the Design Approach-1&2 guidelines of API 674 3rd Edition and Design Approach 1 & 2 according to API 675 ANNEX F. We provide comprehensive solutions to control pressure pulsation and unbalanced shaking forces, ensuring compliance with API 674 standards. Our services include evaluating pulsation dampener capacities in suction and discharge piping networks and recommending additional orifice plates and dampeners as needed.

We also suggest modifications to pipe supports, ensuring they maintain a 20% separation margin from significant pump frequencies and recommending appropriate supports and clamps for the piping system. Our detailed recommendations cover the optimal location and type of support for both suction and discharge piping networks. By implementing these design solutions, we meet the pulsation and vibration guidelines of API 675 and API 674. Additionally, we perform FEM-based harmonic analysis to assess the system’s natural frequency and response to harmonic loads from pressure pulsations. This holistic approach safeguards piping systems’ integrity, prevents mechanical failures and reduces acoustic disturbances, ultimately enhancing the operational efficiency and safety of your plant.
