摘要:

石油化工装置中高压小口径管道防振的设计常被忽视,但其振动问题可能影响装置的安全稳定运行。以某石化合成基础油项目(PAO装置)为例,基于高压往复泵及往复压缩机出入口管道的脉动与振动分析,系统探讨高压小口径管道的优化布置、支架设计及振动控制措施,制定现场振动问题的处理程序。通过对比分析,总结有效的防振策略,为同类管道设计及振动治理提供参考,以提高装置的可靠性和安全性。

Abstract:

 In petrochemical plants, the antivibration design of high-pressure small-bore pipelines are often overlooked, yet vibration issues may compromise the safe and stable operation of the plants. This paper takes a synthetic base oil project (PAO unit) as a case study. By integrating the pulsation and vibration analysis of the inlet/outlet pipelines of high-pressure reciprocating pumps and reciprocating compressor, this article systematically explores the optimized layout strategies, support design, and vibration control measures for high-pressure small-bore pipelines, and proposes systematic troubleshooting procedures for field vibration problems. Through case analysis, effective antivibration strategies are summarized, providing references for the design and vibration mitigation of similar pipelines to enhance the reliability and safety of the plant.

Key words: high-pressure small-bore pipeline, pulsation and vibration analysis; piping design, pipe support design
