✦ Synopsis

Over 30 years heat pipe technology has found many applications in various industries and is proven to be a highly ecient heat transfer technology. There is therefore an emerging problem to ensure the safe operation and long term service life of heat pipes. In the present paper a high temperature life test is conducted on the heat pipes of low-alloy ferritic steels and a stainless steel with alkali metals as working ¯uids. The corrosion mechanisms of the alkali metals at elevated temperature are studied and measures are suggested for improving the design and manufacturing technology of high temperature heat pipes.
