AWWA C207 Flange Bolting
AWWA C207 Flange Bolting
(OP)
Does anybody know when the AWWA C207 standard changed the bolting requirement from only mentioning A307 bolting to A307 bolting for Class B & D and A-193 bolting for Class E & F.
also, AWWA C207-01 lists only A194 nuts regardless of the bolt material in lieu of what can be found in the A307 designation (A563 nuts)
any thoughts on why A-194 nuts would be required for the A307 bolting?
thanks
