【Summary】In the construction process, the use of trenchless drill pipe should avoid diameter drill pipe with small diameter drill pipe, that is, large and small drill pipe mixed use, to prevent the small drill pipe due to insufficient strength to be broken or deformed phenomenon; Before installing the oil drill pipe, it is necessary to clean the female button and male button in time, and put on the thread button oil to prevent premature wear or damage to the button.

Before installing the trenchless drill pipe, the water channel hole should be cleaned in time to prevent the mud system damage caused by debris blocking the channel; It is also necessary to check the wear of each part of the drill pipe, and find out the cause in time if there is abnormal wear. When the scratch trace of the drill pipe body part is about 1mm deep and is in the spiral state for one circle or more, please replace it in time to prevent the trenchless drill pipe from being broken during construction, causing greater losses.
The above non-excavation drill pipe use precautions, drill pipe production factory has many years of experience in the production of non-excavation drill pipe, drill pipe price is reasonable, reliable quality, users can rest assured to buy.
In people's lives can not be separated from a variety of pipelines, in the installation and maintenance of pipelines, mainly the application of trenchless drill for construction. The use of this trenchless technology will not have too much impact on people's lives, but also protect the surface well, and will not produce a lot of dust like excavation technology. Trenchless technology was introduced into China in the 1990s, and it is mainly used in horizontal directional drilling, pipe explosion impact, new pipeline construction and old pipeline repair in water supply, drainage, power, communication, gas and other fields.
The trenchless drill is used in the survey and exploration of mineral deposits, especially those of non-ferrous metals and rare metals, to survey and delineate ore bodies and to sample and verify them. In addition, the work of drilling observation holes, ventilation holes and drainage holes in the tunnel is also implemented by the trenchless drill. In other aspects of tunnel drilling and construction, the application of trenchless drilling rig is also more frequent.
The kelly pipe is located at the upper end of the drill string, and its main role is to transfer the torque and withstand the total amount of the drill string. The end face of the drive part of the kelly pipe is divided into square and hexagon, the more square is used in oil drilling, and the water eye is a regular hexagon, because the wall thickness is about three times that of the drill pipe, and is made of high-strength alloy steel, so it has high tensile strength and torsional strength.MORE
The drill pipe is the hub connecting the surface and the underground. In rotary drilling, the drill string is used to transfer the energy needed to break rock, apply weight on bit to the bottom of the well, and transport drilling fluid in the well. When drilling with downhole power drilling tools, it withstands the reverse torque of downhole power drilling tools and delivers liquid energy to downhole power drilling tools at the same time.MORE
