What are the advantages of commonly thickened rod
2025-01-02The commonly thickened rod has the following advantages: 1. High connection strength: The rough pier process increases the diameter of the two ends or specific connection parts of the drill rod, which significantly increases the contact area when connected to other drilling tools compared to ordinary drill rods. A larger contact area means a more uniform distribution of stress and the ability to

What are the characteristics of surface set diamond core bits
2024-12-12Surface set diamond core bits are mainly used in geological drilling and other fields, and they have the following characteristics: 1. High drilling efficiency Hardness advantage: Natural diamond is the hardest substance in nature, with a Mohs hardness of 10. The diamond particles embedded on the surface protrude from the surface of the drill bit body. During the drilling process, these ha
-
What are the characteristics of oil for rod thread
2024-12-051. Good lubricity One of the characteristics of drill pipe thread oil is its excellent lubrication performance. During the drilling process, the drill pipe needs to be frequently connected and disassembled, and the friction between the threads will generate a large amount of heat. Drill pipe thread oil can effectively reduce the friction coefficient between threads, making the connection and

What are the characteristics of hydraulic pipe twisting machine
2024-11-21The hydraulic pipe twisting machine has the following characteristics: 1. Efficient and labor-saving Mechanized operation: The hydraulic pipe twisting machine is driven by a hydraulic system, which can replace manual labor to unscrew and unload drill rods, greatly reducing the labor intensity of workers. Especially in drilling operations where drilling tools are frequently used, the effect
-
What are the characteristics of the rope core winch
2024-11-14The rope core winch has the following characteristics: 1. Efficient and convenient operation: Reducing auxiliary operation time: Rope core drilling is a drilling method that can directly obtain rock cores without lifting the drill. The rope core winch, combined with this drilling process, does not need to frequently lift the entire drill rod to the surface when salvaging the inner core tub
-
What are the characteristics of the Trojan horse gripper
2024-11-07The Trojan horse gripper has the following characteristics: 1.In terms of structure and principle: Utilizing eccentric structure: mainly composed of eccentric seat, shaft, slip, connecting rod, crank, etc. During operation, the two eccentric seats with elliptical hammer heads rotate downwards along their pivot points, pushing the slip forward to clamp the clamped object such as the drill r
