Spherical threads function v-formed threads exactly where the crest and roots are rounded. The benefit of this thread is the fact that it has fantastic liquid sealability. Even so, this thread provides inadequate tensile resistance and can only aid masses lesser than 80% on the pipe overall body resistance. 

Thickness design and style on two ends of the drill pipe improves exhaustion resistance efficiency and provides pipe an extended company existence;

Regular max upset Proportions are specified in API 5DP, but the exact dimensions on the upset are proprietary to the maker.
