Method of controlling gas pressure pulsation and pipe vibration in the pipe In order to control the gas pressure pulsation and pipe vibration in the pipe, the analytical design method is specified in the machine manufacturer in API-618. Pulsation is controlled using a patented or empirically designed pulsation suppression device. If there is a stipulation in the contract, the buyer's piping system should be simply analyzed. To avoid the resonance of the gas column, determine the length of the important pipeline. This method does not require acoustic simulation analysis. As for which of the three analytical design methods is required for machine builders to perform pressure pulsation and vibration control, there is a recommended form in API-618 (see ). As can be seen from the table, the greater the machine power and the higher the outlet pressure, the more detailed the analysis is required. The specific requirements for the machine manufacturer to adopt which method should be determined by the buyer and the seller according to the analytical conditions and requirements of the manufacturer. There is no direct correspondence between the magnitude of the amplitude and the fatigue damage. The direct impact on the fatigue damage is the cyclic stress value. The most fundamental control indicator for pressure pulsation and pipe vibration in API-618 is the peak-to-peak value of the pipe cyclic stress. API-618 stipulates that the cyclic peak-to-peak value of the cyclic vibration generated by the vibration of the pipeline shall not exceed the fatigue endurance limit of the material in consideration of the stress concentration factor. For carbon steel pipes with operating temperatures below 371e, the fatigue endurance limit is 17912 MPa. Although Tier 1 and Tier 2 do not calculate cyclic stress, the above criteria are still the most fundamental guiding principle of these two methods. Limitation of gas pressure non-uniformity in the tube is required in API-618 to limit the value of gas pressure non-uniformity in the tube. The analysis design method is different and the allowable values ​​are different. But all of these limitations are fundamentally to meet the limits of cyclic stress peak-to-peak. When the following pressure non-uniformity requirements are met, the peak-to-peak requirements for cyclic stress can be satisfied under normal conditions. Conclusion The vibration of reciprocating compressor pipeline is a problem often encountered during machine operation. This paper discusses the process and method of anti-vibration design of reciprocating compressor pipeline from the perspective of pipeline design, and explains the problems that should be paid special attention to in the design. The anti-vibration design practice of dozens of reciprocating compressor pipelines shows that the method is effective and reliable. As long as appropriate anti-vibration measures are taken in the pipeline design stage, the vibration problem of the pipeline can be avoided.
