Hi All,

In ASME B16.5 there is a note relating to intermediate strength bolts (e.g. SA-193 B7M). Refer to Table 1B (Note 3) of ASME B16.5.

The note says that "These bolting materials may be used with all listed materials and gaskets, provided it has been verified that a sealed joint can be maintained under rated working pressure and temperature".

Could someone help me in explaining what the exact requirement means by Sealed joint. Can this requirement be checked by calculations using PV Elite or Code Calc.

Regards
GS
