On the other hand, a U-tube exchanger is only connected to the tubesheet and shell on one end, allowing for thermal expansion without harm to the rest of the machine. U-tube designs also allow for the tube bundles to be easily removed from the exchanger. This aids in easy inspection and cleaning of the shell and outside of the tube bundle.
Three types of Shell & Tube Heat Exchangers:Fixed Tube sheet, U-tube and Floating Tube sheet. The Fixed Tube sheet design consists of two stationary tube sheets attached to the shell. The bundle of straight tubes is connected between the tube sheets and contains baffles to direct the flow around the tubes in order to generate the required heat transfer. Shell and Tube Heat Exchanger:Design & Water Flow
For straight tube heat exchangers, very thin single tubes are guided straight through a large pipe. They can be operated according to the parallel flow principle or counterflow principle. The straight tube heat exchanger only generates a very low pressure loss during operation. It is available in an upright (vertical) or horizontal design. Types of Shell and Tube Heat Exchanger LinquipApr 21, 2021 · U-tube heat exchanger design (Reference:en.wikipedia) Most shell and tube heat exchangers have either 1, 2, or 4 passages on the tube side. These numbers refer to the times the fluid in the tubes passes through the shell. Straight Tube Heat Exchanger
Jun 07, 2021 · A heat exchanger with U-tube packages takes up slightly less volume than a straight tube heat exchanger of the same design due to the bent individual tubes. Here also the concept of u tube vs straight tube heat exchanger comes to the scene. During the action, u-tube heat exchanger often provides only a low-pressure loss. Choosing between a straight tube and a U-tube designFeb 17, 2016 · Choosing between a straight tube and a U-tube design There are many factors to consider when designing a shell and tube heat exchanger. These include cost, application and the limitations of the facility in which it will operate. One decision every manufacturer will have to make is whether it will be a straight tube or a U-tube exchanger.
