Description
In the U-shaped tube heat exchanger, each tube is bent into a U shape, and both ends are fixed on the same tube plate, and each tube can be freely expanded and contracted to solve the problem of thermal compensation. There are at least two tube passes, the tube bundle can be pulled out for cleaning, and the tubes can expand freely. The disadvantage is that it is difficult to clean the inner wall of the tube, it is difficult to replace the tube, and there are few tubes arranged on the tube plate. The advantage is that the structure is simple, the weight is light, and it is suitable for high temperature and high pressure conditions.
