How to judge the quality of the drill rod-beneficial mining technology.
The drill rod is a tool for connecting the drill bit and rock drilling in the well and roadway engineering. The drill rods generally used in mine shaft engineering are hexagonal hollow steel and hollow circle steel. The inner diameter of hexagonal hollow steel is 22mm and 25mm, and the outer diameter of hollow circle steel is 32mm and 38mm. The steel rods include finished steel rods and forged steel rods. The finished steel rods are forged according to a certain length and then installed with drill holes. The forged steel rods are cut with hollow hexagonal steel as required, and then the drill ends and forging machines are used to forge. The quality of the drill rod depends on the steel type, heat treatment process, the structural design of the drill rod, the transition between different sections, and even.

Classification of drill pipe joints-Yikuang Technology
A drill pipe is a steel pipe with a threaded tail that is used to connect the surface equipment of the drilling rig to the drilling equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to carry drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. Today we mainly come to understand the drill pipe joint, the drill pipe joint is an integral part of the drill pipe, the male joint and the female joint, connected to the two ends of the drill pipe body. In order to enhance the connection strength of the joint, the wall thickness of the pipe body needs to be increased at the joint part. According to the thickening method, it can be divided into: internal thickening, external thickening, internal and external addition

What are the advantages of twist drill pipe-beneficial mining technology
Twist drill pipe is a consumable tool accessory used in coal mines. The high-efficiency twist-shaped drill pipe used in coal seam drilling rigs is made of high-quality carbon steel and is suitable for coal electric drills. This is an essential tool for coal mining. Twist drill pipe is mainly divided into two kinds: dry twist drill pipe and wet twist drill pipe. Twist drill pipe and all kinds of pneumatic anti-outburst drilling machine supporting the use of factory, the use of spiral drilling technology, with drilling speed, drilling forming good, drilling efficiency and other characteristics. Compared with the traditional drilling speed greatly increased. Twist drill pipe products are one of the essential equipment in mining. Mining requirements are becoming more stringent. If certain attachments are to be used in a mine,

Structure and working principle of rib drill pipe
The structure of the 1. rib drill rod The rib drill rod is mainly composed of two parts: the rod body and the rib piece. On a core tube similar to an outer flat drill pipe, a high-hardness blade with a certain width (generally about 18mm) and a certain height (generally about 7mm) is helically welded, and processed to make its outer diameter consistent with that of the outer flat drill pipe, as shown in fig. 2. Fig. 2 main specifications of rib drill rod: φ 50-φ 63.5, φ 63.5-φ 73, φ 73-φ 89 cases: rib drill rod φ 73-φ 89 refers to the diameter of the drill rod body is φ 73mm, and the outer diameter of the rib piece (I .e. the outer diameter of the drill rod) is φ 89mm. 2. ribs
