Product Description

AWWA C207 Class D Steel Blind Flange 
 
AWWA C207 Class D steel ring flanges are available in sizes 4″ through 144″. These flanges have the same OD and drilling pattern as Class 125 cast-iron flanges (ASME B16.1). In sizes 24″ and smaller, they also match ASME B16.5 Class 150 drilling for steel flanges. The maximum pressure (test or transient) allowed can be up to 262.5 psi for 4″~12″ Class D slip-on ring flanges, and 225 psi for sizes larger than 12″ slip-on ring flanges.
