High-Quality NQ-HQ-PQ Drill Rods Drill Pipes Factories, Pricelist

All rods longer than 5 ft/1.5 m are heat treated for better wear resistance in all drilling applications.

Manufactured to strict quality standards. We control and verify every rod thread and adapter we make.

Product Description

The Feature of Our Geological Drill Rods

Enhanced Durability: Case hardening on rods end protects thread connection and increases wear resistance and rod life.
Deep Hole Drilling: Our wire-line rods are specifically designed and suitable for deep hole drilling operations.
Standard Lengths: Standard effective length is 3 meters. Custom lengths are available based on special requirements.
Heat Treatment: Chemical heat treatment technology increases thread wear resistance dozens of times over.

We have many years of experience in manufacturing coring drill rods. With a large inventory always in stock, we focus on providing the most cost-efficient products without compromising quality.

Drill Rod and Casing Specifications

Our drill rods and casings are manufactured using premium quality cold-drawn seamless tubes and high-grade tools for diamond core drilling. These alloy steel tubes ensure excellent tensile strength and elongation characteristics, processed via high-technology CNC machines.

By integrating the latest technological developments, we manufacture upseted drill rods. Using tubes with larger internal diameters where the wall thickness of both ends is increased for threading, the final product is significantly lighter. This results in rig depth capacity increases of up to 30%. The heat treatment process further ensures durable and resistant threads.

Frequently Asked Questions

What materials are used in your drill rods?
We use premium quality cold-drawn seamless alloy steel tubes to ensure high tensile strength and durability for diamond core drilling.
Are the drill rods suitable for deep hole drilling?
Yes, our wire-line rods are specifically designed to meet the requirements of deep hole drilling operations.
What is the advantage of upseted drill rods?
Upseted rods are significantly lighter due to their design, which can increase the depth capacity of drill rigs by up to 30%.
How do you ensure the longevity of the thread connections?
We apply case hardening and chemical heat treatment to the rod ends, which protects the thread and increases wear resistance manifold.
Can I request a custom length for the drill rods?
While the standard effective length is 3 meters, we can manufacture other lengths based on your specific project requirements.
What series are available in your standard catalog?
We provide NQ, HQ, and PQ series with various diameters and thicknesses to suit different drilling needs.
