Drill string
The pipe that connects the rig to the bit
Drill pipe carries the bottom-hole assembly, turns it, and is the conduit for drilling fluid. Heavy-weight drill pipe is the transition to the drill collars, which put weight on the bit. Edatm supplies those tubulars against API Spec 5DP and API Spec 7-1 when the order names those specifications.
- Outside diameter, grade, connection and range are the quotation.
- Collars and heavy-weight pipe are separate lines on the same enquiry if you want them.
- The photograph is drill pipe. It is not a picture of every grade.
