Sandvik Shank Adapters is a steel pipe with a ribbed 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 well. The purpose of the drill pipe is to transport the 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, the drill pipe can be used many times.
Explanation on the conditions of use of drill rods:
1. The rated torque of the selected drill rod should be greater than the large torque of the drill rig. The rotating speed of the drilling rig should be less than the rotating speed of the drill rod (the impact of the drill tool moment of inertia on the drill rod is less than the rated torque of the drill rod).
2. In a certain stratum, when the sum of the weight of the drill rod is not extended to make the drill teeth of the drill tool eat into the original soil layer, it is not allowed to use the friction drill rod to drill.
3. When using friction drill pipe to drill oblique holes, it must be well guided in the direction of expansion and contraction of the drill pipe when using the protective tube and drilling tool, and the angle between the center lines of the pipe sections must not exceed 0.4 degrees.
4. Drilling a vertical hole and the inclination of the hole exceeds the hole inclination stipulated in "JTJ041-2000 Highway Bridge and Culvert Construction Technical Specifications", which is likely to cause damage to the High Air Pressure DTH Hammers.
