Product name: T51 Thread 1525mm Length Diamond MM Extension Rod For Underground Coal Mine Equipment

Product category: Drilling rod

Threaded Connection: T51

Length: 1525mm

KINGDRILLING Alloy steel with a high strength is used to make threaded drill pipes. High-precision CNC machines are used to machine all tracks and threads. Rapid heating and cooling are used to induce the threads after induction hardening. The mechanical qualities of the drill pipe are enhanced and its service life is guaranteed by precision temperature control heat treatment equipment.

Total carburization hardens the outer steel body and raises the carbon content of the drill pipe's outer layer. Drilling activities in complicated rocks and terrains can be completed with great precision and efficiency by using solid thread drill bits that fit exactly against the inner wall of the drill bit.

FAQ:

1. How are drill pipes connected?
When thicker drill pipes are joined on the inside and outside using a full-hole type connection, the result is a drill pipe joint with an inner diameter that is smaller than the pipe's inner diameter. The thickened end diameter and the inner diameter of the drill pipe junction are the same.

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:

Our pipes are designed to resist the toughest circumstances, whether you're working in rocky or abrasive soil. This reduces downtime and extends the equipment's lifespan. With our precisely designed drill pipes, you can get the best possible drilling performance. Our pipes, which are made for low friction and effective energy transfer, make drilling operations go more smoothly and enable you to finish projects more quickly and accurately.
