Our Advantages
Superior Raw‑Material & Mature Heat‑Treatment Technology
Our drill rods are manufactured from premium‑grade alloy steel. We carry out quenching and tempering treatment for rod bodies and hardening treatment for connecting threads. Excellent torsion‑resistance, fatigue‑resistance and abrasion‑resistance effectively lower the frequency of rod breakage, thread damage and underground loss during long‑time high‑intensity drilling work.
Flexible Custom‑Made Service Oriented to Different Working Conditions
Different geological strata and drilling equipment require matched drill‑string parameters. Our factory supports non‑standard customization over outer diameter, wall thickness, rod length, thread specification, surface treatment and export‑packaging. Our technical staff will recommend suitable drill‑rod configurations according to your local rock condition and drilling‑rig parameters.
Strict Multi‑Procedure Quality‑Control System
From raw‑material composition inspection, CNC precise thread machining, heat‑treatment to finished‑product ultrasonic flaw detection and torsion‑load testing, every working procedure is supervised. We can provide material test reports and factory inspection certification for customs‑clearance and third‑party checking.
Integrated Supply‑Chain and Worry‑Free Overseas Service
Apart from threaded drill rods, we can supply couplings, adapter subs, DTH hammers, drill bits and all drilling‑rig accessories. We arrange safe sea‑freight packaging and container‑loading. Once you meet assembly‑or‑wear‑related troubles, our drilling‑tool engineers offer timely online technical guidance, and we guarantee the quality of factory‑defective goods.
FAQ
Q1. What material are your drill rods made of?
A. Our drill rods adopt high‑strength alloy steel. We supply DTH drill rods, water‑well drill pipes, and extension rods.
Q2. Can I customize the length, diameter, and thread type?
A. Yes. We support OEM customization for outer diameter, rod length, male‑female thread specification, and surface hard‑banding.
Q3. Are your drill rods compatible with most brands of drilling rigs?
A. Our connecting threads comply with mainstream industry standards and fit most domestic and overseas crawler drill rigs, down‑the‑hole hammers, and water well drilling machines.
Q4. What shipping terms can you provide?
A. EXW, FOB, CIF, and DAP services are optional.
Q5. Can I ship drill rods along with drilling rigs and spare parts in one container?
A. Absolutely. Combined loading for drill rods, drill bits, crawler drilling rigs, and mobile air compressors helps you cut down ocean shipping expenses by 15%‑20%. Our team will work out a reasonable container layout.
Q6. What common reasons cause drill-rod break-off?
A. Main causes contain over‑torque loading, thread abrasion, rod bending from deviated boreholes,s, and improper thread lubrication.
Q7. Do you offer an after‑sales quality guarantee?
A. We carry out strict quality inspections before shipment. For manufacturing‑caused defects, we provide free‑of‑charge replacement.
Q8. Could your team give me a technical suggestion to choose a proper drill rod?
A. Tell us your borehole depth, rock hardness, drill-rig torque, and working environment. Our professional drilling-equipment engineer will recommend suitable rod diameter, steel grade, and thread style.
