Shell and tube heat exchangers are important equipment in the process flow of industries such as oil refining, chemical engineering, and power. According to statistics, this equipment accounts for approximately 40% of all static equipment in refineries. It is not only the main equipment in the process flow, but also the main means for enterprises to reduce energy consumption and costs. Therefore, the technical level of shell and tube heat exchangers is one of the main indicators of the advanced level of refineries.

THT Juyuan, as a major manufacturer in China's heat exchange equipment industry, is a manufacturing base for shell and tube heat exchangers with a production capacity of 10000 tons. The company holds the design license and manufacturing license of special equipment (pressure vessel D1, D2) in the China, and has more than 100 specifications of shell and tube heat exchanger series products, which are suitable for professional needs in different fields and industries. The entire process of product design, manufacturing, inspection, and service complies with the requirements of the ISO9001 international quality system and the provisions of GB150-1998 "Steel Pressure Vessels", GB151-1999 "Shell and Tube Heat Exchangers", and "Safety Technical Supervision Regulations for Pressure Vessels".

Shell and tube heat exchangers are one of our company's main products, with many unique features in the structural design, product manufacturing, and application technology of heat exchangers; In addition to possessing conventional design and manufacturing technology for shell and tube heat exchangers, we are mainly committed to developing and processing high-efficiency shell and tube heat exchangers with enhanced heat transfer components. We have made significant technological innovations in the field of enhanced heat transfer, which has enabled Juyuan Company's shell and tube heat exchangers to have efficient and stable characteristics. Compared with the ordinary smooth tube heat exchanger, the selection of various enhanced heat transfer means significantly improves the heat transfer efficiency, reduces the Friction loss, and realizes the high matching between the heat transfer efficiency and the resistance drop. Among them, spiral tube, arc tube, baffle rod, and spiral baffle plate heat exchangers are national patented products independently developed by our company, with performance and quality reaching the international advanced level. The products have been widely used in various industries such as petrochemical, oil refining, light industry, power, metallurgy, and water conservancy.

Product composition

The shell and tube heat exchanger is composed of main components such as a tube box, shell, and tube bundle. The tube bundle is the core of a shell and tube heat exchanger, where the heat exchange tube serves as a thermal conductivity component that determines the thermal performance of the heat exchanger. Another basic component that has a significant impact on the thermal performance of heat exchangers is the baffle plate (or baffle rod). The tube and shell mainly determine the pressure bearing capacity and safe and reliable operation of the tube and shell heat exchanger.

operational principle

Shell and tube heat exchangers belong to inter wall heat exchangers, and the fluid channels formed inside the heat exchange tubes are called the tube side, while the fluid channels formed outside the heat exchange tubes are called the shell side. When the tube side and shell side pass through two different temperatures of fluids, the higher temperature fluid transfers heat to the lower temperature fluid through the heat exchange tube wall. The higher temperature fluid is cooled and the lower temperature fluid is heated, thereby achieving the purpose of the two fluid heat transfer process.
