Data proves strength
We leverage quantifiable production capacity, testing coverage, and export experience to support the delivery of every engineering project.
Establishing long-term reliability through process stability
From materials, welding, heat treatment to finishing, we standardize key processes to ensure consistent quality even in mass production.
Large-tonnage friction welding process
To achieve stable connection of dissimilar materials, improve welding strength and reduce the heat-affected zone.
High-precision CNC machining
Threads, connectors, and key dimensions are processed and inspected in a standardized manner to ensure interchangeability and wear resistance.
Complete drilling tool solution
We offer suitable drilling tool combinations for scenarios such as down-the-hole drilling, water well drilling, reverse circulation drilling, and rotary drilling.
A clear path from operating conditions to delivery
We focus more on the actual construction conditions of our customers, rather than just providing a list of models.
Requirements understanding
The actual working conditions are confirmed starting with the borehole diameter, rock strata, equipment, and delivery location.
Solution matching
Complete matching sets are made around drill pipes, drill bits, connectors, and material grades.
Stable delivery
Project delivery is supported by standardized production, testing, and packaging processes.
Place quality control at every stage of production.
Consistent delivery comes from enforceable production standards and process re-inspection, rather than a final inspection.
- Raw material batch traceability and warehousing inspection; Friction welding, heat treatment, and finishing process control; Thread accuracy, coaxiality, and surface quality re-inspection.
Complete product ecosystem
We offer a portfolio of drilling tools covering multiple scenarios, focusing on drilling efficiency, connection strength, and field durability.
High-strength alloy steel materials such as 55SiMnMo, 35CrMo, and 42CrMo are commonly used, and the structure and heat treatment are optimized according to different working conditions.
Employee Profiles
Team moments in real workshops, testing facilities, and project sites.
