Product Description /DESCRIPTION
U-tube bundle heat exchanger is a kind of shell-and-tube heat exchanger. It belongs to petrochemical equipment and consists of main components such as tube box shell and tube bundle. It is named because its heat exchange tube is U-shaped. The U-tube heat exchanger has only one tube plate, and both ends of the tube are fixed on the same tube sheet.
Product Features /CHARACTERISTIC
The characteristic of such a heat exchanger in Shandong Kanglu is that the tube bundle can be freely stretched and not generated due to the temperature difference between the tubes and shells. The thermal stress compensation performance is good; the tube length is double tube process, the flow rate is higher, the heat transfer performance is better. The pressure bearing capacity is strong; the tube bundle can be taken out from the casing for easy maintenance and cleaning, and the structure is simple and the cost is low. However, the tube in the middle part of the tube cleaning tube is difficult to replace, and the bending radius of the inner tube is not too small. The tube is not compact in the central part of the tube sheet, so the number of tubes cannot be too large and there is a gap in the central portion of the tube bundle to make the shell-side fluid easy to short-circuit. In addition, in order to compensate for the shell-side heat transfer, in order to make up for the thinning of the pipe wall after the pipe bending, it is necessary to use a thicker pipe. This affects the use of the pipe. It is only suitable for the case wall temperature difference or shell-side medium. Easy to scale and the tube medium is clean and difficult to scale. High temperature and high pressure corrosive.
