| Abstract: | The types and operating principle of heat exchangers are explained. Causes of failure are analyzed for heat exchangers widely applied in refining u-nits and chemical units from the viewpoints of corrosion and sealing element failure. Deficiencies in aspects of process, operation, type selection, equipment, engineering design, construction and quality control may all contribute to the failure of heat exchangers. Corresponding countermeasures are put forward. |
