Drill pipe, is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).
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,
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
