Product Description

Make to Order gas boiler Heat Exchanger



The structure of Tubular Heat Exchanger is simple, compact and cheap, but it can't be cleaned by machine. The tube bundle of the heat exchanger is connected to the tubesheet, which is welded at both ends of the shell, and is connected with a top cover. The top cover and the shell are equipped with fluid inlet and outlet nozzles. A series of baffles perpendicular to the tube bundle are usually installed outside the tube. At the same time, the connection between the tube and the tube sheet and the shell is rigid, and there are two kinds of fluids with different temperatures inside and outside the tube. Therefore, when the temperature difference between the tube wall and the shell wall is large, due to the different thermal expansion of the two, a great temperature difference stress will be produced, so that the pipe will twist or loosen from the tube sheet, and even destroy the heat exchanger.

In order to overcome the temperature difference stress, there must be a temperature difference compensation device. Generally, when the temperature difference between the pipe wall and the shell wall is more than 50 ℃, the heat exchanger should have the temperature difference compensation device for the sake of safety. However, the compensation device (expansion joint) can only be used when the temperature difference between shell wall and pipe wall is lower than 60 ~ 70 ℃ and the fluid pressure in shell side is not high. Generally, when the shell side pressure exceeds 0.6MPa, due to the thickness of the compensation ring, it is difficult to expand and expand, so other structures should be considered.
