What is the working principle of diamond core bits? The drill bit that makes the cutting edge is called a diamond core bit. The drill bit is an integrated drill bit. The entire drill bit has no moving parts. The structure is relatively simple, with high strength, high wear resistance and impact resi
What kinds of drill pipe can be divided into? The drill pipe is a steel pipe with thread on the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device located at the bottom end of the drilling well. The purpose of t
How to classify core barrels? A section of pipe connected to the upper part of the drill bit to accommodate and protect the core during core barrel.

Product Description:
DTH Drill Rod Drill Pipe
Down the hole drill pipes 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. Roschen DTH drill pipes are made of superior alloy and the both thread ends are friction welded to the seamless steel pipe. The high pressure air is delivered to DTH hammer by DTH drill pipe, simultaneously it transfers the rotation and press force to the DTH hammer.

Roschen can produce various types of non-excavation drill pipe, water well drill pipe, Exploration Core drilling drill pipe, DTH drill pipe, petroleum drill pipe, geological drill pipe, anchor drill pipe, 100B DTH drill pipe 50 drill pipe friction welding drill pipe, all our drill pipe produced by friction welding.
Drill pipe and drilling tool features:
1. High-precision CNC lathe processing to ensure the tightness of the thread connection;
2. Special heat treatment process to ensure that the connecting thread has sufficient strength and wear resistance;
3. The body of the drill rod and the joint are welded by a friction welding process, and then the intermediate frequency return is used to remove the welding stress to ensure the welding strength and the straightness of the finished drill rod.
4. The drill rod body and joint are made of European and American high-quality raw materials to ensure the superiority of normal construction under harsh conditions.
