U-tube refers to a heat exchange tube shaped like a U, which is an important part of a U Type heat exchanger. Advantages of U-shaped tube: The U-shaped tube heat exchanger has only one tube plate, both ends of the tube are fixed on the same tube plate, the tube can be stretched freely, no thermal stress, and the thermal compensation performance is good; the tube side adopts double tube side, The process is longer, the flow rate is higher, the heat transfer performance is better, and the pressure bearing capacity is strong. The tube bundle can be drawn out from the shell, which is convenient for maintenance and cleaning, and the structure is simple and the cost is cheap. The disadvantage of the U-shaped tube is that due to the limitation of the radius of curvature of the bend tube, the arrangement of the heat exchange tubes is less, the innermost tube spacing of the tube bundle is relatively large, the utilization rate of the Tube Sheet is low, and the shell-side fluid is easy to form a short circuit, which is harmful to the transmission. When the tubes are leaked and damaged, only the U-shaped tubes at the periphery of the tube bundle are easy to replace. If the inner heat exchange tube is damaged, it cannot be replaced, but can only be blocked. Moreover, one damaged U-shaped tube is equivalent to two damaged tubes, and the scrap rate is relatively high.
