Bolted joint - Bolt Spacing

[Graybags]

Hi,

My application is a bolted cover for a swing check valve.

Is there a design code/empirical rule of thumb that dictates maximum bolt spacing. My calcs take into account the y and m factors, however, how can i be sure that the gasket will not leak mid way between bolts?

Thanks in advance

Generally, If you design the gasket, bolting and cover to ASME VIII the likelyhood of gasket leakage is slight.

That said, having many years in valve design...TEST!
