Stainless steel tube heat exchanger 304 condenser

Stainless steel tube heat exchanger is an efficient industrial heat exchange equipment, and its introduction is as follows:

-Structural composition: mainly composed of shell, tube plate, heat exchange tube, head, and baffle plate. The shell contains fluid and protects the internal tube bundle; Tube plates are used to fix heat exchange tubes and connect them to the shell; Heat exchange tubes are the main channels for heat transfer; Seal both ends of the shell with a sealed head to maintain fluid tightness; The baffle supports the tube bundle, guides fluid flow, and improves heat transfer efficiency.

-Working principle: Based on heat conduction and convective heat transfer, the hot fluid flows inside the tube and the cold fluid flows outside the tube (shell side), and the two exchange heat through the tube wall to achieve heat transfer.

-Material characteristics: It is usually made of austenitic stainless steel or duplex steel such as 304 and 316L, which has good corrosion resistance and can resist corrosive media such as acid, alkali, and salt. At the same time, it can withstand high temperatures of 400 ℃ and high pressures of 1.6MPa.

-Structural types: mainly including fixed tube plate type, floating head type, U-shaped tube type, packing box type, etc. The fixed tube plate structure is simple and cost-effective, but it is prone to thermal stress when there is a large temperature difference; Floating head type is suitable for large temperature differences and easy to clean, but it has a complex structure and high cost; U-shaped tube type is resistant to high temperature and high pressure, without leakage, but difficult to clean; The stuffing box is suitable for corrosive media and has a narrow range of applications.

-Performance advantages: It has strong corrosion resistance, high temperature and high pressure resistance, high heat transfer efficiency, easy maintenance, compact structure and other advantages. Its comprehensive heat transfer coefficient can reach 14000W/(m ··℃). The tube bundle is detachable, easy to clean and maintain, and the volume is only 1/5 of traditional heat exchangers, which can save infrastructure investment.

-Application areas: Widely used in chemical, petroleum, power, food, pharmaceutical and other industries, such as reactor cooling and distillation tower reboiler in the chemical industry, steam condensation and cooling water circulation in the power industry, milk pasteurization and juice concentration in the food industry.
