Introduction to the characteristics of diamond compact drill bits
Diamond composite sheet (PDC) is a special superhard material synthesized by synthetic diamond and hard alloy at one time under high temperature and high pressure. It not only has the advantages of high diamond hardness and wear resistance, but also has the characteristics of hard alloy, such as strong impact and large cutting edge. All over the country's coal fields, oil drilling, water conservancy and hydropower, railway, highway, tunnel construction and other industries.

Design and Application of Rib Drill Pipe in Coal Mine
The drill pipe is one of the main components of the drilling tool. During drilling, the power is transmitted to the core pipe, the drill pipe and the drilling tool. Due to the complex underground geological conditions, a hole with a depth of 100 meters is likely to contain both soft and hard strata. The traditional drill pipe cannot meet the drilling requirements under this special condition, which brings great difficulties to the underground drilling work, it is not conducive to the transformation and development of enterprises, so it is very important to find a solution to the problem. Through the analysis of drilling equipment, field working environment and construction formation, the whole process of traditional drill pipe drilling is studied.

The difference between friction welding drill pipe and integral drill pipe
Friction welding drill pipe is a solid-state welding method in which two drill pipes are connected together by friction welding technology. (Under the action of pressure, the material is deformed by the friction interface of the workpiece to be welded and the temperature in its vicinity, accompanied by plastic rheology of the material, and welding is realized through molecular diffusion and recrystallization of the interface.) The welding can reach the strength of the forging structure, which can be comparable to the base metal in theory.

The material of geological drill pipe is the main factor affecting the life of the drill pipe.
There are many reasons for the fracture of the drill pipe, which should be listed one by one. First of all, the material of geological drill pipe is one of the main reasons, today's market drill pipe material is more chaotic, many businesses in order to get more economic benefits will be shoddy. Since there are such low-cost products, there will be cheap users who buy them at low prices and have no ability to distinguish quality. The consequences are not worth the loss. What's more, some users buy inferior pipes at high prices. The consequences are the same.

How to use the rib drill pipe reasonably
According to the torque, push-pull force and allowable minimum curvature radius of the drilling rig, select the appropriate specification and model of the rib drill pipe. During construction, it is prevented that the large diameter rib drill pipe is connected to the small diameter rib drill pipe (I. e. the large and small rib drill pipes are mixed) to avoid the small rib drill pipe being broken or deformed due to insufficient strength.

Highway guardrail pile driver installation matters needing attention
With China's modernization process slowing down, highway guardrail pile driver way to build faster and faster, more and more highways in my territory loud, with the improvement of people's life and death degree, the car also has in every family, the method of war is becoming more and more people's attention, highway anti-collision guardrail installation is an important career method to add property and calm. Everyone knows that the pile drilling machine will be used to equip the anti-collision guardrail, and the small editor will discuss with you on the road some attention to the construction of the barrier piling machine.

Introduction of Friction Welding Drill Pipe Advantages of Friction Welding Drill Pipe
Friction welding drill pipe, also known as imitation British drill pipe, friction welding drill pipe body using high-quality alloy structural steel material, after non-destructive testing and performance inspection qualified rear end for rough treatment, after rough full-length heat treatment, improve the toughness and strength of the pipe body, drill pipe joints using high-quality alloy structural steel with strength better than the pipe material. The thread is made on a high-precision CNC lathe, and the thread part is heat-treated to meet the toughness requirements of the rod body and the strength requirements of the joint.

Structure and Process Performance Characteristics of Triangular Drill Rod
Triangular drill pipe can be stably drilled in soft and outburst coal seam, reducing the in-hole accidents such as holding drill and drill pipe fracture that often occur when using ordinary drill pipe. Through the design and improvement of the structure and parameters of triangular drill pipe, the process flow, welding process and heat treatment process of triangular drill pipe are analyzed and optimized.

Talk about the matters needing attention in cleaning and maintenance of drill pipe joints
The 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 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. In the process of oil and gas extraction and refining, drill pipe can be used many times.
