Dear Team,

can anyone tell me about the reference standard for WN flange dimensions over 60" to 100"?.

Up to 60" it can be covered under B16.47 B series. but what about over sized flanges?.

Best regards,

4T4, a bit of googling turned up this catalog containing several standards for large diameter flanges.

Regards,

Mike

The problem with sloppy work is that the supply FAR EXCEEDS the demand
 
thanks mike for sharing the doc,

also i have the attached a spec which is superseded.

since it is for effluent treatment plant, i would rather check with ASTM F 1311 too. because the pressure rating may not be a major issue here.
