Flange torque specs?
(OP)
I am trying to find the recommended torque for cast iron flanges, 3" and 4" 150#, and 4" 300# flange. Can anyone point me in the right direction?

jmilano ...Not sure if it is clear, but 150# & 300# are ASME ratings for forged steel flanges ...as Duwe6 pointed out. 125# & 250# are cast iron ratings.
According to pg. 162 of my Tube-Turn Catalog 411
..."detailed flange calculations are made following the Rules for Bolted Flanged Connections in Section VIII (Unfired Pressure Vessels Code) of the ASME Boiler Construction Code"
