Can a weld neck flange be bolted to a slip-on flange and if so, which torque load would be applied from the torque tables. RFWN or RFSO?

RE: Can a weld neck flange be bolted to
Why do you think there is a difference in torque between SO and WN flanges? I can't see how the flange face is bothered what type of connection it has to the rest of the pipe, but please enlighten me if you can show two different torques for the same flange.

RE: Can a weld neck flange be bolted to
I have a set of torque tables that show RFWN and RFSO torque values for their respective flanges. Although most torque values are the same, on occasions there are some diffences, usually with the higher flange sizes. For example: a 14" 300# Weld neck has a torque setting of 512 lbs.ft, whereas a 14" 300# Slip-on is shown as 415 lbs.ft. In cases such as this, which torque setting would be used?

I can't see why there should be a difference so it's difficult to say. B16.5 doesn't say anything about different types of flanges needing different mating forces.
Different torque tables exist and different figures exist varying by bolt strength, degree of lubrication, use of washers etc.

a bad-fitting flange over-tightened by a air hammer one bolt after another will leak faster than an under-torqued pair of aligned flanges properly sequenced in a star-pattern but 85 ft-lbs too little.
