Description
Standard:API 5DP drill pipe, API SPEC 7 Standards
Size: 60.3 ~ 168.3mm
Grade: E75,X95,G105,S135
Upset Type: EU, IEU
API 5DP drill pipe internal Coating:High abrasion resistance and low friction factor,
High hardness and impact resistance, Good corrosion resistance
Hard-banding: Good balance between anti-wear and friction-reduction; The wear rate is less than 6% of that of the bare tool joint, which can prolong 3 times of the tool joint service life; Reduce the torque of drilling string; Good weldability with a little splash and good re-welding performance
