Oilfield drill pipes compliant with API 5DP, API 7‑1, and NS‑1 standards, covering steel grades E75, X95, G105, S135, SS95, SS105, SS135, as well as V150 and U160, are specifically designed for oil exploration and production wells. They are available with NC, IF, FH, REG, PAC, SLH, and DS thread connections and are supplied with complete Material Test Certificates (MTC) and 100% Nondestructive Testing (NDT) reports.
API 5DP gas drill pipe is specifically designed for drilling natural gas wells. It is manufactured from high‑strength steel grades and is available in sour‑service specifications suitable for environments containing hydrogen sulfide (H₂S). It is supplied with a complete Material Test Certificate (MTC) and has undergone 100% nondestructive testing (NDT).
API‑standard drill pipe, available in diameters of 73 mm, 89 mm, 102 mm, 114 mm, and 127 mm, with steel grades DZ50, R780, and G105. Custom lengths and thread types are supported, offering a cost‑effective drilling solution.
Geological drill rods suitable for mineral exploration, coalfield geology, and nuclear‑industry drilling. Featuring a straight‑joint design with exceptional fatigue resistance; custom thread options are available to ensure seamless compatibility with a wide range of original‑equipment drills.
Type A light‑weight drill collars feature a smooth cylindrical surface. They are suitable for vertical wells and can deliver maximum weight on bit. Compliant with API 7‑1 standards, they are manufactured from AISI 4145H alloy steel. Available in sizes ranging from 3‑1/8 inches to 11 inches.
Type B spiral drill collar, featuring right-hand helical grooves. It reduces contact area with the wellbore wall, minimizing differential sticking while maintaining drilling‑weight transmission and structural rigidity. Compliant with API 7‑1 standards and available in custom sizes.
C‑type nonmagnetic drill collars for MWD directional drilling. Manufactured from N1310 low‑carbon alloy steel to prevent magnetic interference. Certified to API 7‑1 standards. Available in sizes ranging from 3‑1/8 inches to 11 inches.
Square‑section drill pipe compliant with API 7‑1 standards. Manufactured from high‑strength alloy steel for reliable torque transmission. Fully heat‑treated and subjected to nondestructive testing (NDT), with custom dimensions available.
Hexagonal drill rods compliant with API 7‑1, featuring a hexagonal cross‑section. Manufactured from high‑strength alloy steel and subjected to full‑length heat treatment. Ensure smooth engagement with the rotary table and reduced wear. Custom sizes available.
API conversion joints designed to connect different thread types and sizes. Available in male–male, male–female, and female–female configurations. Manufactured from 4145H alloy steel. Standard lengths are 36 inches or 48 inches, with custom thread combinations also supported.
API lifting subs for pipe handling operations. Available in Type A (18° shoulder) and Type B (90° shoulder), manufactured from high-strength alloy steel. Provide attachment points for lifting equipment and support custom dimensions.
LW Series Wear-Resistant Belts: LW600 (extends joint life by 1.2 times), LW700 (extends joint life by 1.8 times), LW800 (extends joint life by 2.4 times). They can reduce casing wear by 70–85%. No cracks, no spalling. Compliant with API 7CW standards.
We can customize high-performance drill pipe assemblies of various sizes according to customer needs.
