Extension Drill Rods, Drifting Drill Rods
The extended drill rod of a rock drill is a special type of drill rod used on a rock drill (also known as a drilling rig or rock drill) to increase the drilling depth when drilling in rocks, concrete, or other hard materials. Extended drill rods are usually made of high-strength alloy steel, which has sufficient strength and durability to cope with harsh drilling environments.
Here are some detailed information about extending the drill rod of a rock drill:
Materials: Extended drill rods are usually made of high-strength alloy steel, such as 4340 steel, 30CrMnSiA, etc. These materials have high yield strength and tensile strength, and can withstand high torque and high pressure during the drilling process.
Structural design: The design of an extended drill pipe typically includes a threaded male joint and a threaded female joint for connection with other drill pipes or drill bits. These joints usually use special connection mechanisms, such as spiral locking or conical locking, to ensure that they do not fall off during the drilling process.
Length: The length of the extended drill pipe can be customized according to needs, with common lengths ranging from 1 meter to several meters. The choice of appropriate length depends on specific drilling requirements, such as drilling depth, rock hardness, etc.
Diameter: The diameter of the extended drill pipe is also determined according to specific needs, with common diameters ranging from 32mm to 115mm. Choosing the appropriate diameter can ensure compatibility between the drill pipe and the drill bit, and optimize the drilling effect.
Surface treatment: In order to improve the wear resistance and corrosion resistance of drill pipes, some extended drill pipe surfaces will undergo special treatment, such as sandblasting, painting, or coating.
Safety precautions: When using extended drill rods, it is necessary to ensure compatibility with the rock drill and other accessories, and to install and use them correctly according to the operating manual. In addition, it is also necessary to pay attention to keeping the drill pipe clean and lubricated to extend its service life.
Application areas: The extended drill rods of rock drills are widely used in mining, tunnel construction, basic engineering, geological exploration and other fields. They can be used to drill holes of different diameters and depths to meet various engineering needs.
In short, extending the drill rod of a rock drill is an important drilling tool, which is of great significance for improving drilling efficiency and effectiveness. When selecting and using extended drill rods, it is necessary to comprehensively consider specific needs and pay attention to following relevant safety operating procedures.
