Drill pipe is made from the welding of at least three separate
pieces: box tool joint, pin tool joint, and the tube. The ends of
the tubes are then upset to increase the cross-sectional area of
the ends. The tube end may be externally upset (EU), internally
upset (IU), or internally and externally upset (IEU). Standard max
upset dimensions are specified in API 5DP, but the exact dimensions
of the upset are proprietary to the manufacturer. After upsetting,
the tube then goes through a heat treating process. Drill pipe
steel is commonly quenched and tempered to achieve high yield
strengths
