Fixed Tube Heat Exchanger

fixed tube heat exchanger The structure of fixed tubesheet heat exchanger is simple, compact and cheap, but cannot be cleaned mechanically. This tube bundle of heat exchanger is connected ontubeplate, which is welded on both ends of the shell, the top cover connected are equipped with fluid inlet and outlet nozzles.A series of baffles perpendicular to the tube bundle are usually installed outside.Two different temperatures fluids inside out, therefor regid material is used. Therefore, to avoid thermal expansion between tubes inside out when temperature difference is higher than 50°C, automatic temperature compensator needs to be installed.However, the compensation device can only be used in the case that the pressure of the shell side fluid is not high when the temperature difference between the shell wall and the pipe wall is less than 60-70°C. Generally, when shell side pressure exceeds 0.6Mpa, because compensation ring is too thick, it is difficult to expand and…
