Effect of temperature difference on the expansion amount of heat exchangers
Thread Content
Within what temperature range difference between the hot and cold fluids in a heat exchanger is it not necessary to install expansion joints?
The last edit to this post was made by Yi-*aoshan on 2016-11-30 at 09:40. The temperature difference between the shell and the tubes is kept within a moderate range (roughly speaking, it is generally believed that it should be
According to the book \"Heat Exchanger Process Design\" compiled by Sun Lanyi and others, on page P78, the sixth line from the top states that if the metal temperature of the shell and tubes exceeds 30°C or 50°C, or if the maximum temperature difference between the cold fluid inlet and the hot fluid inlet exceeds 110°C, then the use of a fixed-tube heat exchanger without expansion joints will result in uneven thermal stresses and leakage.
