Characteristics of three-rowed drill pipe, what are the causes of invalid geological drill pipe?

In the overall design, the rod body adopts the triangular pyramid structure, which can best reflect the characteristics of environmental protection, energy saving and high efficiency in production and application. Therefore, it is called the triangular pyramid high-efficiency friction welding drill pipe, generally called the three-edged drill pipe.

In addition, in the design scheme, the profit maximization of the screw gauge geological drill pipe with the same drill pipe is ensured.

Because the six square connection mode is adopted, the drill pipe can be equipped with the best torque and comprehensive physical performance under the same diameter standard, which can best reflect the overall goal of the design scheme to maximize the profit of drill pipe torque.

The special horizontal drill pipe is connected with spring yellow collet spring, which can prevent the external thread of the drill pipe from getting stuck and the screw head from breaking.

In addition, horizontal drill pipe spring yellow card spring installation and disassembly convenient, save cost. Compared with external thread or anchor bolt fixed fixed pin, the working efficiency is further improved.

In today's rapid economic development, the development trend of machinery manufacturing industry is also rapid development, drill pipe in the ordinary production and manufacturing theme activities play an increasingly key role, drill pipe is divided into geological drill pipe, non-geological drill pipe and so on. The non-slotted drill pipe is a special tool used to transfer the drilling machine torque and tensile force into the construction site, because it must bear distortion, tensile force, bending, friction, vibration in the construction site, so its production process is very strict. However, due to the limitation of the main production level, it is often found that the drill pipe has the condition of shrinkage with strip in the ordinary processing process, which seriously endangers the quality of drill pipe and the life of diamond head. According to the heat treatment process of drill pipe, this problem is solved, which has a key effect on improving the quality of drill pipe.

The main method of drill pipe failure is the fracture of drill pipe. If the drill pipe is broken in the whole process of guiding and definite drilling, it may cause relatively serious harm to the project, which is not only a great loss in economic development, but also a harm to the construction period, loss of credibility and unpredictable adverse effects. Therefore, as the engineering construction PDC bit myself or the company, must learn how to correctly select and apply drill pipe.

To understand the specific requirements of various foundation pit excavation or trenchless pipe jacking projects to produce drill pipe with high toughness, high wear resistance and high reliability. Non-geological drill pipe is invalid, and we can analyze it from two aspects: human error and the flaw of drill pipe itself, the flaw of drill pipe itself can be divided into the flaw of design scheme and the flaw of raw material itself.
