What is the production process flow for shell and tube heat exchangers?
Thread Content
What is the production process for fixed-tube-sheet shell-and-tube heat exchangers? The key is how the tubes, tube sheets, shell, and tube sheet boxes are connected A tube sheet with flanges is used. Is it that the tube sheet, tubes, baffle plates, tie rods and other components are connected first, then the shell is fitted over them, and finally the tube sheet box is attached? In that case, since the tube sheet has flanges, how can the shell be fitted over it? Can only use a single tube sheet with flanges? I’m completely puzzled and would be extremely grateful if anyone with practical production experience could offer some guidance!
:( :( :( :( Where are the seniors? It’s a small favor – please help me out.
I wonder what you do? Are you a student? Have you just graduated and started working? I suggest spending some time in a manufacturing factory – then everything will become clear!
Students are currently busy working on their graduation projects and don’t have time to go for practicals! The day before yesterday I went to a factory near the school, only to find that they weren’t manufacturing heat exchangers – what a disappointment~!
It’s very simple, for reference only: 1. First, make pairing marks on the tube sheet, then draw a straight line on the shell-side cylinder (along the longitudinal direction of the shell-side cylinder). 2. First, connect the baffle, tie rod, and one end of the tube sheet. To increase its stiffness (and prevent the baffle from deforming), a few heat exchange tubes can be inserted appropriately (the heat exchange tubes should not be welded). 3. Fit the aforementioned components into the welded shell-side cylinder (make sure the tube bank alignment marks are aligned with the straight line of the cylinder). Fix the shell-side cylinder and tube sheet. 4. Install the other end tube sheet (make sure the matching marks on the tube box are aligned with the cylinder; introduce the tie rods or some of the heat exchange tubes first, before fixing the shell-side cylinder to the tube sheet to facilitate better positioning). 5. Create a guiding insertion head that is inserted into the heat exchange tube, entering from one end of the tube sheet and exiting from the other end. Insert the heat exchange tubes one by one in this manner; don’t worry about it being troublesome. This post was last edited by cuiwei4260 on 2009-4-18 08:42.]
All can be equipped with flanges; the tube sheet at one end is installed last
