Edesign is a manufacturer of high-quality, durable and customized shell and tube heat exchangers tailored to meet the specific needs of our clients across various industries. Shell and tube heat exchangers are used in many industrial process applications because they are capable of performing a variety of tasks, such as removing process heat and preheating feed water. The cooling of hydraulic and lubricating oils. Heat exchangers are commonly used in oil refineries, compressors and engines to cool turbines, compressors and engines. It is the most common type of heat exchanger used for high-pressure applications, such as in oil refineries or chemical plants. This type of heat exchanger is composed of a shell (a large pressure vessel) containing a bundle of tubes. It is possible to design shells and tubes in a variety of ways. Through holes in tube sheets, the ends of each tube are typically connected to plenums. In nuclear power plants called pressurized water reactors, large heat exchangers called steam generators are two-phase, shell-and-tube heat exchangers that typically have U-tubes. To generate electricity, they boil water recycled from a surface condenser into steam.
