Introduction
The six-party drill rod is widely used in rock drilling and blasting in mining, metallurgy, transportation, water conservancy and hydropower projects. Material selection Shanghai Baosteel23 CrNi3Mo, overall vacuum tempering treatment, thread processing using advanced imported CNC lathe, greatly improving the fatigue strength and impact of the drill rod.
It can be used with Atlas, Porter, Guhe, Gordon Denver, Ingersoll Rand, Montabert and other well-known rock drilling jumbo. With reasonable matching, the continuous service life of the drill pipe can reachAbout 3000 meters.

Maintenance
1, the drill rod needs regular maintenance to determine the maintenance cycle, regular anti-rust and dust treatment.
2. The use of drill rod shall be within the rated drilling distance of the drilling rig, and the matching drill rod shall be adopted according to the technical parameters of the drilling distance.3. The drill rod is made of friction welding of special geological drilling pipes for mining geology and their matching joints, so it has good follow-up and high tensile strength, and can be adapted to drilling and gas discharge in regular. When working in hard rock, coal seam or other special environment, the drilling depth shall be determined according to the physical properties and parameters of the actual material of the drill pipe.
4. When the drill rod and the drill bit are used together, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the condition of the drill and the drill pipe should be paid attention to at all times during the drilling process. In case of sticking, sudden death, etc., stop drilling immediately or drill slowly after returning to ensure that the drill pipe is not bent and flat.
5. When the drill rod is ventilated or ventilated, the drill rod shall be tightly connected during drilling. When the geological drill pipe has seals, such as O-ring seals, attention should be paid to the use of the seals, and the seals should be replaced in time when damage, corrosion and other phenomena occur. After the drilling is completed, do maintenance and cleaning work on the seal.
6. When drilling, the drill rod should be tightened manually to ensure close fit (thread type). It is not allowed to drill directly with the drill to prevent damage to the drill rod.
7. If the bending degree of the drill rod after use exceeds the standard requirements or the thread damage causes the normal operation to be impossible, it shall be scrapped or returned to the factory for repair in time.
8, according to the standard requirements, should ensure the drilling depth of the drill pipe composite geological drilling related requirements to prevent the drill pipe due to the drilling depth to reach the limit of the use of the drill pipe, the occurrence of falling off phenomenon.
9. When working in acid and alkali areas, attention should be paid to the corrosion of drill pipes. When drilling is completed, clean the surface of the rod body with clean water in time to remove the corrosion layer.
10. The drill rod shall be stored in a dry place, the bottom shall be supported at multiple points, and the drill rod shall be regularly maintained during long-term storage.
11. The drill rod shall not be used as a supporting platform for heavy tail stacking, and the drill rod shall not be randomly placed under gravel, coal pile or scattered pile.
12, drill rod maintenance after rust removal/dust cleaning should buckle protective cap or packing seal to ensure that the drill pipe is often new.
