89mm
A versatile mid-range option offering balanced strength and flow capacity for most standard water well drilling operations.
114mm
Heavy-duty diameter designed for deep wells, high torque demand, and challenging geological formations.
Excellence Engineered into Every Detail
We understand the demands of harsh drilling environments, which is why we integrate cutting-edge technology and premium materials into every aspect of our design.
Superior Materials for Unmatched Strength
We select high-grade alloy steels like G105/DZ50 to deliver exceptional tensile and torsional strength, enabling you to tackle complex geology and greater depths with confidence.
Advanced Friction Welding for a Flawless Bond
Utilizing state-of-the-art solid-state friction welding, we create a weld joint that is stronger than the parent pipe material, fundamentally eliminating the risk of breakage common with conventional welding.
Full-Length Heat Treatment for Lasting Durability
Every drill pipe undergoes a rigorous full-body quenching and tempering process, ensuring uniform mechanical properties, superior fatigue resistance, and a significantly longer service life.
Precision-Machined Threads for Reliable Connections
API standard threads are precision-cut on CNC lathes, guaranteeing tight, reliable connections that facilitate smooth make-up/break-out and prevent galling.

How We Build Reliable Drill Pipes
Our drill pipes are produced through a tightly controlled, high-precision workflow that ensures strength, consistency, and long-term reliability—from material selection to final inspection.
Material Verification & Upsetting
Inspect raw steel tubes and tool joints, then upset pipe ends for enhanced strength.
Precision Machining
CNC-machine tool joints and pipe ends to ensure accurate threads and connection integrity.
Friction Welding & Heat Treatment
Molecular-level friction welding followed by full-length quenching and tempering to optimize mechanical performance.
NDT, Final Inspection & Coating
Conduct ultrasonic or magnetic particle testing, verify dimensions and threads, then apply protective coating before shipment.
An In-Depth Look at Our Core Technologies
Our drill pipes feature friction-welded joints for maximum strength and full-length quenching and tempering, ensuring uniform hardness, toughness, and superior fatigue resistance for long-lasting, reliable performance in demanding drilling conditions.
Friction Welding Technology
Unlike arc welding, friction welding doesn’t melt the metal; it uses frictional heat and high-speed rotation to soften it.
Strong pressure then forges the pieces together, creating a dense, uniform joint as strong as or stronger than the base material, with a small heat-affected zone that maintains the material’s toughness.ils:
Full-Length Quenching & Tempering
We insist on heat-treating the entire drill pipe, not just the ends. This means the entire pipe body achieves uniform strength, hardness, and toughness.
This provides superior fatigue resistance when subjected to complex bending and vibrational stresses downhole, resulting in a service life far exceeding that of partially treated pipes.

Municipal and Monitoring Well
Applied in urban water supply projects, environmental monitoring wells, and foundational engineering surveys.
Frequently Asked Questions
Have questions? We have clear answers. Here we’ve gathered you need to know about our fly cutter reamer—so you can make your purchase with complete confidence.
Provide our technical team with your rig model (torque and pullback capacity), target drilling depth, and general geological conditions. Our experts will recommend the optimal outer diameter, wall thickness, steel grade, and thread type.
The fundamental difference lies in materials, processes, and long-term value. We use high-grade alloy steel, friction welding, and full-body heat treatment. While the initial investment may be slightly higher, the superior durability and reliability prevent costly downtime from pipe failure, delivering a much lower total cost of ownership.
