Product name: T51 Thread 5530mm Length Diamond MM Extension Rod For Underground Drilling Rig

Product category: Drilling rod

Threaded Connection: T51

Length: 5530mm

KINGDRILLING threaded drill pipes are made of high-strength alloy steel. All tracks and threads are machined by high-precision CNC machines. The threads are induced by induction hardening, followed by rapid heating and cooling. Precision temperature control heat treatment equipment ensures the service life of the drill pipe and improves the mechanical properties of the drill pipe.

Overall carburization increases the carbon content of the outer layer of the drill pipe and hardens the outer steel body. The solid thread can perfectly fit the inner wall of the drill bit, completing various tunnel excavation, underground mineral and open-pit drilling tasks in complex rocks and terrains with high precision and efficiency.

FAQ:

1. In what way are drill pipes joined?
A drill pipe joint with an inner diameter less than the inner diameter of the pipe is produced when the full-hole type connection joins the inside and outside of thickened drill pipes. The inner diameter of the drill pipe joint is equal to the thickened end diameter.

2. Superior product durability:

We use premium materials to ensure exceptional product durability and longevity. This is seen in our drill pipes. Every single pipe is made entirely of one piece, with a forged thickening inside. Industry-leading strength and extended service life are produced by strong wall thickness and one-piece construction. According to our exacting quality standards, every threaded connection is expertly cut.

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.
