Product name: T51 Thread 4270mm Length Diamond MM Extension Rod For
Horizontal Drilling Rig
Product category: Drilling rod
Threaded Connection: T51
Length: 4270mm
KINGDRILLING thread drill
rods are produced from high-intensity alloy steel. All trails and
threads are created using high-precision CNC machines. The thread
is formed by induction hardening, followed by rapid heating and
cooling. Precision temperature-controlled heat treatment equipment
extends the drill
rod's service life and enhances its mechanical qualities.
Holistic carburization raises the carbon content of the drill
rod's outer layer while also hardening the exterior steel body. The
solid thread fits perfectly with the inner wall of the drill bits,
allowing for high precision and efficiency in complex rock and
terrain rough drilling tasks such as roadway tunneling, underground
mineral, and open pit drilling.

FAQ:
1. How are drill pipes connected?
The full-hole style connection connects inside and outside
thickened drill pipes, resulting in a drill pipe joint with an
inner diameter equal to the thickened end diameter, both of which
are smaller than the inner diameter of the pipe.
2. Superior durability of our products:
Our drill pipes are manufactured from high-quality materials,
ensuring excellent durability and longevity. Each pipe has a forged
thickening within its one-piece construction. Thick wall thickness
and one-piece design create industry-leading strength and long
service life. Each threaded connection is precision cut to our
strict quality standards.
3. Optimal performance:
Whether you're working in rocky terrains or abrasive soil
conditions, our pipes are built to withstand the harshest
environments, minimizing downtime and enhancing the overall
lifespan of your equipment. Achieve optimal drilling performance
with our precision-engineered drill pipes. Designed for minimal
friction and efficient energy transfer, our pipes facilitate
smoother drilling operations, allowing you to complete projects
faster and with greater accuracy.
