Regarding the Drill Pipe,the OD from 2 3/8” to 5 1/2” and steel grade from E75 to S135. Mainly used in oil and gas exploration and development process of deep well, horizaontal well and extended reach well. With the Hardbading and Internal Coating.
Hardbanding:
- Avoid drill pipe wear and prolong life
- Avoid friction caused by thernal cracking failure of drilling joints.
- The wear-resisting coefficient has reduced performance with wear casing.
