Slender Pipe Vibration Cracking Analysis and Vibration Reduction Measures

Abstract:

Article Preview

Analyzes that the ammonia plant of a fertilizer between rich liquid line and ammonia synthesis tower of pressure pipeline vibrates some reasons, through the establishment of the pipeline and tower body vibration finite element model, the calculation of the existing constraints stress, vibration frequency and vibration form. By adding a support level and put forward the reconstruction plan of vibration reduction. Through many calculation and analysis, the weld seams stress reduced by 23.6%, the maximum amplitude dropped 98.5% and obtain the better vibration reduction transformation effect.
