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
