6 5/8" API FH Tool Joint thread strength

6 5/8" API FH Tool Joint thread strength

6 5/8" API FH Tool Joint thread strength

(OP)
Can anyone refer me to the API Spec containing either the relevant calculations or tables showing the joint strength of the various API tool joint threads.  I found a table in a string book that I have but it only goes up to 4 1/2".

Any help would be much appreciated.

API RP 7G; Drill Stem Design and Operating Limits might have what you're looking for.
The Spec for the thread itself is API Spec. 7; Rotary Drill Stem Elements but doesn't include operating capabilities.
