Pressurized components of pressure vessels
Thread Content
What are the pressure-bearing components of a pressure vessel? Doesn’t the regulatory standard specify that only the main pressure-bearing components of the pressure vessel itself are considered?
The fixed volume gauge specifies the main pressure-bearing components..1.6.1
I saw it. . Weren’t we talking about the main stressed components? ,.. Is that all?
The fixed volume gauge refers to compressed components; take a close look at items (1), (2), and (3) in 1.6.1.
The code specifies that the main pressure-bearing components include the shell, head (end cover), expansion joint, equipment flanges, the shell plates of spherical tanks, the tube sheets and heat exchange tubes of heat exchangers, the main equipment bolts with a size of ≥M36, as well as the nozzles and pipe flanges with a length of ≥250 mm.
