Xian Mono Technologu Co.,Ltd as API 5DP Drill Pipe supplier,Our Drilling pipe is widely used in oil and gas drilling operations for transmitting drilling torque and circulating drilling fluid under high-pressure downhole environments. Manufactured according to the requirements of API 5DP, our drill pipes offer excellent strength, wear resistance, and reliable performance for both onshore and offshore drilling applications.
We supply API 5DP drill pipe in various grades including E75, X95, G105, and S135 to meet different drilling conditions and operational requirements. Available with standard tool joints and precision machining, our seamless drill pipes ensure stable connections, high torsional resistance, and extended service life in demanding oilfield environments.

Drill Pipe Grades
Drill pipe grades include standard API grades (E-75, X-95, G-105, & S-135), as well as proprietary grades.
API Drill Pipe Grade | Minimum Yield Strength (psi) | Minimum Tensile Strength (psi) |
E-75 | 75,000 | 100,000 |
X-95 | 95,000 | 105,000 |
G-105 | 105,000 | 115,000 |
S-135 | 135,000 | 145,000 |
Drilling Pipe Length:
Range 1 (R1) is shortest in length, more common for sizing production tubing or casing, and ranges from 18 to 22 ft.
Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft.
Range 3 (R3) is common in casing and also deployed in deep water drilling applications. The increased length decreases the number of tool joints in each stand of drill pipe. The fall back being that the load exerted on each tool joint is greater increasing wear and reducing the expected life of the drill pipe. R3 ranges from 38 to 45 ft.
