The spiral drill pipe plays an important role in the drilling process. It transmits the torque of the drilling rig to the drill bit to realize drilling. In the drilling, the geological spiral drill pipe is subjected to a very complex load, almost at the same time under the tension, compression, torsion, bending and other stresses, the quality of the geological spiral drill pipe plays a vital role in the drilling work. Material and processing will cause geological spiral drill pipe to break (1) Geological spiral drill pipe material. Nowadays, the market for drilling materials is relatively chaotic, and dishonest merchants are shoddy. The vast majority of users only consider low prices, but do not have the ability to distinguish the quality of pipes and purchase them indiscriminately. Many users paid a high price and bought it.

(1) Geological spiral drill pipe material. Nowadays, the market for drilling materials is relatively chaotic, and dishonest merchants are shoddy. The vast majority of users only consider low prices, but do not have the ability to distinguish the quality of pipes and purchase them indiscriminately. Many users spent high prices, bought sub-material pipes, and said plausibly how good their things are.
(2) Processing quality. Mainly connecting thread processing standards, processing buckle type, processing quality, processing accuracy and so on.
(3) Heat treatment process. Such as tempering and hardening.
geological spiral drill pipe how to save?
1. avoid moisture
Avoid storage in a humid environment, because the geological spiral drill pipe in a humid environment, the surface covered with moisture and oxygen chemical reaction to form rust, damage the quality of geological spiral drill pipe, and then affect sales. Geological and geological spiral drill pipe should not be placed in places where the temperature is too high and in direct sunlight. Direct sunlight will cause the temperature of the geological and geological spiral drill pipe to rise, expand with heat and shrink with cold, which changes the physical characteristics of the geological and geological spiral drill pipe, resulting in damage or tooth loss during use.
2 Avoid corrosion
The geological and geological spiral drill pipe placed in a corrosive chemical environment, will seriously corrode the surface of the geological and geological spiral drill pipe, generally used in the corrosive environment of geological and geological spiral drill pipe is mostly galvanized or nickel-plated geological spiral drill pipe.
Do you know about the handling and maintenance of geological spiral drill pipes? Take a look at it:
1. Install and check the geological spiral drill pipe, whether the joint is abnormal, whether the size meets the use requirements, take timely treatment measures for the geological spiral drill pipe that cannot meet the use requirements, and strictly prohibit the use of the geological spiral drill pipe that still cannot meet the requirements after taking measures.
2. For the geological spiral drill pipe with critical use requirements, feasible protection measures shall be selected during installation.
3. Protect the surface rigidity of the geological spiral drill pipe joint. It is strictly forbidden to blindly polish the joint without measurement to destroy its surface hardness.
4. During installation, check again whether the joint is complete and the pin hole is smooth, especially whether the pin is in good condition. It is strictly prohibited to use the pin with large expansion and burrs. Hammering the pin must be isolated with rigid and soft materials, and it is recommend to use red copper rod hammering for installation.
5. It is strictly prohibited to use materials with rigidity greater than pin-threading for pin-threading for disassembly type. It is necessary to use symmetrical blow to disconnect the geological spiral drill pipe. At the same time, symmetrical blow is the best. It is strictly prohibited to use vigorous equipment for hammering in a single direction. Forced use is bound to cause hidden damage to the geological spiral drill pipe and frame.
6. The spare geological spiral drill pipe must be rust-proof. For the geological spiral drill pipe stored for a long time, it must be rolled and stored at 180 ° every week to prevent the natural bending of the storage from causing losses.
7. For geological spiral drill pipe pins that are difficult to disassemble, small grinding wheels are preferred to grind holes, electric drills for heating, hammering with impact electric hammers, symmetrical rotation strikes and other methods. Secondly, electric welding and pin puller disassembly are used. Oxygen cutting is really needed to protect the integrity of convex and concave joints as much as possible to ensure that they can be repaired to the original use requirements.
The geological spiral drill pipe should also be regularly maintained, only in this way can the equipment play its effectiveness.
