| Abstract: | The seal principle,structural characteristics,failure reasons,and economy of seal structures used in heat exchangers,subject to high temperature and high pressure in hydrogenation unit,were analyzed and discussed according to the operation conditions of hydrogenation unit.The results of analysis and comparison showed that preferred Ω ring seal,diaphragm seals,followed by the selection thread locking ring seal for use,octagonal metallic ring cushion seal is not recommended. |
| Keywords: | heat exchanger sealing structure high temperature high pressure analysis |
