U tube Heat Exchanger Operate on a simple yet effective principle of transferring heat between two fluied stream without direct contact, one fluied known as the process fluid, flow through the tube, while the others ofen a utility fluid like water or air circulates the tubes with in the shell.
Key Features:
- Large Heat transfer Area: Shell & tube heat exchanger have a large surface area for heat exchange, making them efficient for handling large heat duties.
- High Pressure & Temperature Handling; They can be designed to handle extrema temperature and pressure, making them a good choice for power plant and chemical processing.
- Multi tube Design: The multitube design allows thermal expansion between the tube and shell, which enable the heat exchange to handle toxic and flammable fluids.
- Tube Sheet: The tube sheet is a crucial component that support the large number of tubes heat run horizontally and vertically.
- Tube Pitch and layout: The distance between tubes and their arrangement relative to the shell side baffles flow affect the overall heat transfer and pressure drop.
- Expansion Joint: Expansion joint are often used in shell and tube heat exchanger design to accommodate differential expansion between the shell and the tubes.
Applications:
- Power Generation: Used in steam generators, waste heat recovery and cooling oil and hydraulic fluid in engine.
- Oil & Gas: Used in crude oil Distillation natural gas processing, and Condensing steam.
- Chemical Processing: Used in heating and cooling chemicals, distillations, evaporations, and condensation.
