Yesterday, our factory hosted two Russian clients for an on-site inspection of our advanced drill pipe production facilities. The visit focused on the automation systems that ensure efficiency, precision, and consistent quality in every drill pipe we manufacture.

The guests observed several key processes, including automated cutting of drill pipes and precision CNC thread processing. These high-tech production methods not only improve manufacturing speed but also ensure superior thread accuracy, resulting in better product performance in the field.

Our engineers provided detailed explanations of the production workflow, highlighting the benefits of automated equipment in enhancing operational efficiency, reducing human error, and meeting large-scale order demands with short lead times.

The Russian clients praised the level of automation and technical expertise, noting that such capabilities are essential for meeting the rigorous requirements of modern drilling projects. This visit strengthened their confidence in our ability to deliver reliable and high-performance drill pipe solutions for their operations.

Our drill rods are engineered to deliver exceptional strength, precision, and durability across a wide range of drilling operations, including geological exploration, mining, geotechnical surveys, and horizontal directional drilling (HDD). Manufactured with advanced production technology and stringent quality control, our drill rods ensure reliable performance even in the most demanding environments.

1. Premium Material Selection

We select only high-grade alloy steel, chosen for its excellent tensile strength, impact resistance, and wear resistance. Each batch of raw materials is tested for chemical composition and mechanical properties to ensure consistency and quality.

Rod Material:30CrMnSiA/XJY950
Length per Piece: 3m/1.5m

Types: BQ NQ HQ PQ / NRQ HRQ PRQ
Standard: DCDMA/ Equivalent to Boart longyear/Atlas Copco

2. Advanced Manufacturing Process

Our drill rods are produced through a series of precision-controlled steps:

• Heat Treatment: Optimized quenching and tempering processes provide an ideal balance between hardness and toughness, extending service life.

• Friction Welding: High-strength friction welding ensures a flawless joint between the tube body and the tool joint, minimizing the risk of breakage under high torque.

• Thread Processing: CNC-controlled lathes guarantee accurate, smooth, and perfectly matched threads, ensuring excellent connection stability.

• Surface Hardening: Induction hardening of threads improves wear resistance and prevents premature failure in abrasive conditions.

3. Specifications and Customization

We offer a wide range of drill rod specifications to meet diverse project requirements:

Diameters: Available in standard sizes such as 50 mm, 60 mm, 73 mm, 89 mm, and 102 mm, or customized according to client requirements.

Lengths: Common lengths include 1.5 m, 3 m, and 6 m; custom lengths available.

Custom options are available for wall thickness, surface coating, and special threading to match specific drilling conditions.

• Thread Types: API standard threads, taper threads, and proprietary designs for enhanced sealing and torque transfer.

• Material Grades: S135, G105, and other high-performance grades.
