It is very common to use baffles in the shell side of shell and tube exchanger. They cause the shell side fluid to go across the tubes. This causes 'cross flow' conditions and promotes the overall heat transfer.

Shell and Tube Heat Exchangers Construction Details

The shell-and-tube heat exchanger is by far the most common type of heat exchanger used in industry. It can be fabricated from a wide range of materials both metallic and non-metallic. Design pressures range from full vacuum to 6,000 psi.Shell and Tube Type Heat Exchanger - saVReeIntroduction. Shell and tube heat exchangers, also called tubular heat exchangers, are a common site throughout the engineering world and are one of the two most common types of heat exchanger; the other common type being the plate heat exchanger.. Shell and tube heat exchangers have a simple design, robust characteristics and relatively low purchase and maintenance costs.The effect of plugging of tubes on failure of shell and Common Mechanical Failures in Shell Heat Exchanger TubesOct 01, 2019In shell and tube heat exchangers, deep cracks can occur in tube-to-tubesheet welding and repairing such cracks is an impossible task which makes these tubes totally out of service. To preserve the thermal and mechanical integrity of heat exchanger, a series of rods is passed through these tubes and then are welded to tubesheets from both ends.

Troubleshooting shell-and-tube heat exchangers

a cryogenic exchanger for an over­ all rate of approximately 35. The exchanger was not checked for strati­ fied flow and the tubeside had a low velocity. When the overall rate was back-calculated from the operating temperatures, it was only 6.9.
