Abstract: The bidirectional tensioning structure can play the role of combined reinforcement and precise positioning, which can enhance the strength of tube bundles to achieve vibration resistance, impact resistance and deformation resistance. Such structure can meet the performance requirements of shellandtube heat exchangers with special structures or special process conditions and address issues related to operation, manufacturing, and maintenance of tube bundles. Aiming at the phenomenon that there are fewer public thematic researches and regulations related to the engineering application of bidirectional tensioning structures in shellandtube heat exchanger tube bundles, this paper introduces the bidirectional tensioning structures applied in several different scenarios, explains the engineering principles, and also puts forward suggestions for the future development of the bidirectional tensioning structure engineering technology.
