Abstract: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 amplitud… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
