Issues with internal floating head cover bolts in floating head heat exchangers
Thread Content
The tube side design pressure of the floating head heat exchanger is 6 MPa, with a design temperature of 350 degrees; as a result, the bolts used to secure the internal floating head cover are very thick, causing the nuts to extend beyond the floating head tube sheet； Is that okay?
It’s not good; you can increase the number of bolts or reduce the diameter of the circle centered on the bolts.
Such a design is rare and looks awkward; as mentioned on the second floor, the number of bolts can be increased. If an outer cover can be attached, then this design won’t pose any problems.
It seems like bolts aren’t needed for the floating head cover, right? The floating head flange seems to be welded directly to the arch cover
