Rib spiral drill pipe performance characteristics:
1. what is a rib spiral drill pipe
Rib spiral drill pipe refers to the type of drill pipe welded by pre-stressed winding plane spiral blade with round drill pipe as the rod body. According to the type of spiral blade, it can also be divided into single spiral, double spiral and three spiral type.
1. rib spiral drill pipe features:
Rib spiral drill pipe in the construction process of rotation resistance is small, good slag discharge effect, can be applied to various types of strata, and can be quickly disassembled by disassembly device, improve the construction efficiency, save labor and material costs. Because the spiral blade is wide and has high hardness, the rib spiral drill pipe has good slag discharge effect and is suitable for various hardness and various types of formations. In addition, due to the wider spiral blade, the rib spiral drill rod will not cut the hole wall of the drilling hole during the drilling construction process, and will not cause the hole wall to be inclined and affect the drilling effect. Rib spiral drill pipe is divided into taper thread connection and hexagonal quick plug type.

2. rib spiral drill pipe description:
1. The welded rib spiral drill pipe shall be regularly maintained to determine the maintenance period, and regularly carry out anti-rust and dustproof treatment.
2. The use of welded rib spiral drill pipe shall be within the rated drilling distance of the drilling rig, and the matching drill pipe shall be adopted according to the technical parameters of the drilling distance.
3. Welded rib spiral drill pipe is made of special geological drilling pipe for mining geology and its matching joint by friction welding, 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 welded rib spiral drill pipe is used with the drill bit, 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 welded rib spiral drill pipe is ventilated or ventilated, the drill pipe shall be tightly connected during drilling. When the drill pipe has a seal, such as O-ring seal, pay attention to the use of the seal, in the event of damage, corrosion and other phenomena, to replace the seal in time. After the drilling is completed, do maintenance and cleaning work on the seal.
6. When drilling, the welded rib spiral drill pipe shall be tightened manually to ensure close fit (thread type). It is not allowed to drill directly with the drilling rig to prevent damage to the drill pipe.
7. If the bending degree of the drill pipe after use exceeds the standard requirements or the thread damage causes the normal operation to be impossible, the drill pipe 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 welded rib spiral drill pipe shall be stored in a dry place, and the bottom shall be supported at multiple points. During long-term storage, the drill pipe shall be regularly maintained.
11. Welded rib spiral drill pipe shall not be used as a supporting platform for heavy tail stacking, and shall not be randomly placed under gravel, coal pile or scattered stacking.
12, welded rib spiral drill pipe maintenance rust removal/dust cleaning should buckle protective cap or packing seal to ensure that the drill pipe is often new.
Select the drill pipe, please identify the beneficial mining drilling tools.
