Steps for unlocking the auger drill pipe
The drill pipe of the rotary drilling rig can drill dozens or even hundreds of meters of pile holes. It turns out that the drill pipe is nested inside the drill pipe layer by layer. Today, I will talk to you about the unlocking steps of the spiral drill pipe. Screw unlocking step 1: the most important thing to unlock is the resistance of the drill bucket, and the drill pipe is unlocked by it. this is especially important. screw unlocking step 2: when the resistance of the drill tool is fixed to the core section, the drill pipe and the core section in the third section are unlocked. Step 3 of spiral unlocking: when the core section and the third section are fixed by the resistance of the drilling bucket, the second section and the third section are unlocked. Screw Unlock Step 4: Move

Significance of Quick-connect Spiral Drill Pipe for Coal Mine Industry
China is a country with huge coal reserves, and the coal mining industry still has great potential in China. It is very common to use quick-connect spiral drill pipe in the coal mining industry. Here we will analyze the significance of spiral drill pipe for China's coal mining industry! From the perspective of the total amount of coal reserves in the country, thin and extremely thin coal seams are widely distributed in China, and the specific distribution is listed in Table 1-1. More than 80 of the country's original 95 key mining bureaus and 455 mines have thin and extremely thin coal seams. The reserves of thin and extremely thin coal seams in key state-owned coal mines across the country are 2.529 billion tons, of which Shanxi, Hebei, Sichuan, Inner Mongolia, Guizhou and Chongqing have reserves of 1.799 billion tons of thin and extremely thin coal seams. In addition, the coal seam reserves of Datong, Kailuan, Xuzhou and Pingdingshan mining areas reach 0.501 billion tons. According to statistics, the reserves of thin and extremely thin coal seams in China account for more than 20% of the total recoverable reserves, while the output of thin and extremely thin coal seams only accounts for about 10% of the total output, which is far lower than the proportion of its reserves, and has a further downward trend. Throughout the national coal mining industry situation, thin and very thin coal seam mining problem is more and more prominent, and this problem is an overall unavoidable problem. As an indispensable fast-connecting spiral drill pipe in the coal mining industry, its contribution to the coal mining industry is unparalleled. The majority of the coal mining industry also puts forward higher requirements for the performance of fast-connecting spiral drill pipe. Here we remind everyone to look for professional production enterprises when buying fast-connecting spiral drill pipe and avoid buying defective products! shandong yi mining drilling technology co., ltd. production of drilling engineering dedicated to all kinds of geological drill pipe, spiral drill pipe, triangular drill pipe, coal drill pipe, drill bit, drill pipe, complete specifications!

Causes and dangers of low pressure brittle fracture of geological drill pipe!
Causes and dangers of low pressure brittle fracture of geological drill pipe! A drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the drilling. 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. Geological drill pipe geological drill pipe low pressure brittle fracture causes and dangers! Low stress brittle fracture of geological drill pipe accounts for a large proportion of the whole drill string failure, and its risk is also very high. Low stress brittle fracture occurs in both drill pipe and drill string conversion joints. Such

Beneficiation Technology-Characteristics of Double Shoulder Joint of Triangular Drill Pipe
Triangular drill pipe is a geological drilling tool that is widely used in China and is produced by conflict welding process planning of geological alloy steel pipe. Considering the special geological conditions and different terrains, there are certain requirements for the bending strength, fatigue strength and shear strength of the geological triangular drill pipe. Therefore, in the purchase, on its raw materials and production process to do to deepen the understanding. Characteristics of double shoulder joint of triangular drill pipe 1. Increase the torsional strength of the joint 2. Adopt streamlined optimization design to increase the inner diameter of the joint, thus significantly reducing the circulating pressure loss along the drilling tool and reducing the outer diameter of the joint, thus
