Being on the gulf coastal, and the bad location of cooling tower systems in our units. My question is, using standard CS A105 flanges with A193 B7 bolting, is it true that bolts in the flanges act as controller of the rusting problem, and will rust before the flanges, but if hot dipped bolting was used for the flanges the flanges would rust out faster than with A193 b7 bolting?
