Davis,
In API Spec 6A, the maximum Recommended Flange Bolt Torque is calculated
with a bolt stress of one-half the yield stress. Tabulation found in
Appendix D. The API specs are referred to in many ANSI standards. API 6A:
Wellhead and Christmas Tree Equipment includes design with ring joint and
metallic gasketing.

Subject: [PipingDesign] Mil-Spec question?
Good Morning All,
Does anyone know of an ASTM or ANSI standard that discusses torque ratings for bolts?
I am currently reviewing a military specification, and I have come across something odd, if you have ever read one you would understand. There is a statement in a paragraph that states:
"Maximum torque ratings for flange bolts as specified in standard ANSI specifications for flange bolt specifications shall not be exceeded."
I'm having a hard time figuring out where this is?? Can anyone help??
Sincerely,
