Product Description
Manufacturer Water Well Drill Rod Oilfield Pipe With Thread Drill High Quality DTH Drilling Rod
Introduction to drill pipe
Drill pipes that are used in applications such as DTH/ DTHR/ DR basically comprise of a steel tube with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools.
DTH drill tubes are used for connecting DTH hammer and DTH button bits; they are made from seamless tubes. Tubes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability. According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice avers. Usually we are offering 50mm, 60mm, 76mm, 89mm, etc. ALL DTH drill tubes are friction welded, and usually the threads are standard API connections,like23/8" API REG thread, 3 1/2" API REG thread or API IF thread, etc. According to customers request, from 1000mm to 5000mm length of tubes are available.

Advantages
1. The drill rod body is made of high quality geological special alloy steel pipe, and the drill rod joint is made of high
quality alloy structural steel. After vacuum quenching and tempering treatment, the fatigue strength and shear strength are largely improved.
2. Adopting advanced friction welding technology, the drill pipe has the characteristics of high bending strength and strong welding.
3. The production equipment completely adopts advanced CNC processing equipment, high production efficiency, high quality and stability.
4. It can guarantee the straightness requirements in deep hole drilling. This product has high fatigue strength and long service life.
5. According to the actual needs of users, we can design and produce various special specifications and performance drilling tools.
