Heat exchanger head
Thread Content
If required by the process, can the jacket of this head be directly welded to the flange neck, provided that the flange is not a jacketed flange? Or rather, it can only be redesigned in a fully jacketed structure.
I don’t know how to apply textures; I used a screenshot tool to take a screenshot, but what was sent ended up as garbled characters

That’s it; it’s in the form of a welding jacket marked with red lines

Welding is possible; the groove on the jacket needs to be properly prepared, and it must not interfere with the insertion of bolts
Next, as mentioned by #8, from a manufacturing perspective, the approach suggested by the original poster is not impossible, but it is necessary to ensure that it does not interfere with the installation and removal of bolts. Moreover, if there is an insulation layer in place, its placement must also be carefully considered, along with the impact of any structural changes on the insulation effectiveness. Not all structures are designed that way for no reason :)
Then, #8 said that from a welding perspective alone, the structural changes mentioned by the original poster aren’t impossible, but it’s necessary to ensure that they don’t affect the installation and removal of bolts. Moreover, if there is an insulation layer present, it’s also important to assess how such structural changes will affect the installation of that insulation layer. No structure is designed in its current form without a reason :)
No. Generally, the jacket structure is welded only to the main body of the equipment, trying to avoid fittings, connections, etc. The main considerations are: ease of takeover, maintenance of welds that connect the accessories to the main equipment body, non-destructive testing, and regular inspections.
