API 5CT Coupling OD

[calimechengr]

API 5CT released a new edition in July 2011: API 5CT 9th Edition. Would anyone be able to provide me the coupling OD for Long Casing, specifically 7" and 5 1/2".

Although the 9th edition was published in July 2011, it does not become effective untill Janurary 2012.

On the 5 1/2", there was no change. The 7" increased a bit, 7.875". Of course, that is assuming that I understand what it is you want, since the "Long" generally refers to the coupling, not the casing, and you are dealing with 8-round threads.
