To overcome the shortcoming of complicated structure of floating-head heat exchanger and remain the advantages that the tube bundle of floating-heat exchanger can be pulled out and the thermal stress can be eliminated, U-tube heat exchanger has been developed. U-tube heat exchanger is a kind of heat exchanger whose tubes are bent into U-shape and both ends of the tubes are fixed on the same tube sheet.

1. Advantages of U-tube heat exchanger

1) Simple structure saves a piece of tube sheet and a channel. The manufacturing cost of U-tube heat exchanger is low;
2) The tube bundle and the shell are separated, so they cannot restrain each other and the thermal stress is eliminated when they are heated.
3) The tube bundle can be pulled out from the shell, and the outside tube is cleaned easily.

2. Main disadvantages of U-tube heat exchanger

1) When the tube is bent, a certain radius of curvature must be ensured. So a larger space, whose width is twice as large as the outside diameter of heat transfer tube, exists in the middle part of tube bundle to make the fluid flow the short pass easily, bad for the heat transfer. Therefore, a piece of middle baffle is mounted in the middle of the tube bundle, to prevent the short pass of fluid and improve the heat transfer efficiency.
2) It is hard to clean the inside of tube, so the clean media and the media not easy to scale should flow in the inside of tube.
3) When the tube is damaged to cause the leakage during operation, other tubes cannot be replaced except that the outermost tube of the tube bundle can be replaced. At that time, the leaked tube will be blocked off, to decrease the heat transfer area.

U-tube heat exchanger is generally used in the services with high temperature and high pressure. When the U-tube exchanger is applied at higher pressure, the heat transfer tube with thicker wall should be adopted to compensate the thickness reduction of tube wall caused by bending tube. Some residual stresses remain on the tube wall during the tube bent, so the annealing treatment should be carried out after bending the tube.
