As shown in the figure, there is a device similar to a baffle on the fixed tube sheet (below a size of 45 mm). What is its function? Could the seniors give some guidance on its pattern structure?
This is a lug used with shoulder studs; it serves to provide positioning and prevent loosening. On pipe sheets, usually 2 or 4 of these are installed depending on the number of bolts and the diameter of the equipment
Thank you very much for the reminder, thanks. Following your reminder, I found it in clause 6.17.3 of the standard GB/T151.
