Natural Gas Shell And Tube Heat Exchanger Hot Sale

Description

Shell and tube heat exchangers still dominate the heat exchange equipment used in chemical production. Although it is not as good as other new heat exchange equipment in terms of heat exchange efficiency, compact structure and metal material consumption, the shell and tube heat exchanger has the advantages of solid structure, large operation flexibility, strong adaptability, high reliability and a wide range of materials. , large processing capacity, can withstand high temperature and high pressure and other characteristics, so it is still widely used in engineering.

Specification

product structure

Shell-and-tube heat exchangers consist of shells, heat transfer tube bundles, tube sheets, baffles (baffles) and tube boxes. The shell is mostly cylindrical, with tube bundles installed inside, and both ends of the tube bundles are fixed on the tube sheet. Two fluids, hot and cold, for heat exchange, one flows inside the tube, called the tube side fluid; the other flows outside the tube, called the shell side fluid. In order to improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed in the shell. The baffle can increase the velocity of the fluid on the shell side, forcing the fluid to pass through the tube bundle several times laterally according to the prescribed path, and enhance the degree of fluid turbulence. The heat exchange tubes can be arranged in equilateral triangles or squares on the tube sheet. The equilateral triangle arrangement is compact, the fluid outside the tube has a high degree of turbulence, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube, and is suitable for fluids that are prone to scaling.
