Heavy weight drill pipe is the tool used as a transition between the normal drill pipe and the heavier drill collars. In some applications, heavy-weight drill pipe may also be used in place of the drill collar. The performance standard for heavy weight drill pipe is API Spec 7-1.
⊙We could offer the welded and intergrated type HWDP.
⊙A center upset could increase HWDP life, reduce hole drag and differential sticking problems.
