Fixed-tubesheet heat exchanger is a kind of exchanger which the tube sheets in both sides fixed with the shell by welding.

Fixed-tubesheet heat exchanger is a kind of exchanger which the tube sheets in both sides fixed with the shell by welding. The steel tube and the fin pipe can be used to be the heat pipe. It is applied broadly in engineering, because its simple structure, low manufacture cost. It can get not only the smaller interior diameter of the shell, but also the tube and sheet side can be divided into several types, complete ranges of specifications.

Fixed-tubesheet heat exchanger is made up of the shell, tube sheet, tube bundle, top(head) and etc. The parallel tube bundle can be fitted into the round shell. The two ends of the tube bundle make fast by welding or bulging on the tube sheet,two boards of the tube sheet are welded with the tube directly, the top with the tube in or out is connected with the flanges on both ends of the shell.

In Chemical Production, the fixed-tubesheet heat exchanger is fit for the two distinct occasions: the one is the difference in temperature between these two different mediums isn’t big, and the other is that the difference in temperature is big, but the pressure of the shell isn’t high, the medium of the shell is clean, and it isn’t easy to scale formation.

It features simple structure, makes it easy to produce and both sides of the shell aren’t connected hermetically.

When the interior diameter of the tube is the same, the number of the tube can be placed is the highest. The openings at the either side are the smallest in the material flowing with the baffle plate. The tube side can be devided into any sides. In all kinds of the Shell-and-tube Heat Exchangers, the tube sheet of it is the thinnest and the cost of it is minimal, because the two tube sheets are supported by the tube.
