U-tube heat exchanger application field and application advantages

The U-tube heat exchanger adopts advanced electro-polishing process, combined with advanced metal expansion welding processing technology, optimizes the minimum gap design of the heat exchange tube, reduces the wall thickness as much as possible under the condition of ensuring safe operation, and greatly improves the cold The heat transfer effect of the thermal fluid is several times that of the traditional heat exchanger under the same conditions. It improves the work efficiency under the premise of clean and hygienic, and reduces the comprehensive production cost during the long-term operation.

U-tube heat exchanger means that in the shell-and-tube heat exchanger, the heat exchange tubes are respectively connected with two tube sheets. In this kind of heat exchanger, the two sides of the same element are the tube side medium and the shell side medium, and the middle part has only the heat exchange tube. Therefore, only the leakage of the heat exchange tube body will cause the tube side medium to mix with the shell side medium, and the possibility of this leakage is far less than the connection between the heat exchange tube and the tube sheet and the flange connection of the floating head tube box. leakage. Therefore, when the tube side medium and the shell side medium are strictly required to be immiscible, a double tube plate heat exchanger can be used.

The U-tube heat exchanger is suitable for heat exchangers suitable for high temperature, high pressure and high temperature difference in the heat exchanger. Its U-shaped tube tail end can float freely, without considering the temperature difference stress, and can be used in high temperature difference occasions; and there is only one tube plate, a small number of flanges, a simple structure and few leakage points, and low manufacturing costs; in addition, it can be core-pulled Clean.

All in all, U-tube heat exchanger should use U-tube structure. At the same time, considering the influence of the medium, in order to prohibit the mixing of the medium in the shell and tube side, which will produce strong corrosive hydrochloric acid or hypochlorous acid, which will cause more serious corrosion to the equipment, this equipment adopts a tube sheet structure.

U-tube heat exchangers have been used in a wide range of fields, including cooling of pasteurized purified water, cooling of water for injection, heating of circulating water for injection water, cooling and heating of pharmaceuticals, and high-purity solutions. Heating, cooling and sterilization, and heating, cooling, evaporation, crystallization, and sterilization in industrial processes such as various foods, beverages, fruit juices and beer.

U-tube heat exchangers are used in occasions where the medium between the tube and the shell side is absolutely prevented from mixing. For example, for a heat exchanger that takes water in the shell side and chlorides in the tube side, if the water in the shell side comes into contact with the chloride in the tube side, it will produce highly corrosive hydrochloric acid or hypochlorous acid. Process materials cause severe corrosion. The U-tube heat exchanger adopts a double tube plate structure, which can effectively prevent the two materials from mixing, thereby preventing the occurrence of the above-mentioned accidents.
