Regarding the common sense that should be mastered when purchasing geological drill pipes, Xiaobian thinks that we can start from the following points: 1. usually think of whether the model, specification and parameters meet the requirements when purchasing engineering equipment, and the purchase of geological drill pipes is nothing more than these. 1. Geological drill pipe standard structure Geological drill pipe is a kind of drilling tool that uses alloy steel pipe to thicken the upsetting head at both ends, turn the small pitch taper thread, and connect with the lock joint. It is used in the field of geological exploration, transmits the torque of the drilling rig to the bottom hole drill bit, and is responsible for transmitting drilling fluid. Drill pipes are divided into 1 meter, 2 meters, more than 3 meters and more than 4 meters in length. Customers can choose according to the depth of drilling. Drill
About the common sense that should be mastered when purchasing geological drill pipes, Xiaobian thinks that we can start from the following points:
1. usually buy engineering equipment will first thinkWhether the model, specification and parameters meet the requirementsThe purchase of geological drill pipes is nothing more than these.
1,Geological drill pipe standard structure
Geological drill pipe is a kind of drilling tool that uses alloy steel pipe to thicken the head at both ends, turn the small pitch taper thread, and connect with the lock joint. It is used in the field of geological exploration, transmits the torque of the drilling rig to the bottom hole bit, and is responsible for transmitting drilling fluid. Drill pipes are divided into 1 meter, 2 meters, more than 3 meters and more than 4 meters according to their length.,CustomerCan be drilled accordingDepth of the wellto choose.Drill pipes can be divided into 40,50,60 and 89 drill pipes by size,The 50 drill pipe has a wide range of applications and is more practical for hitting soil, rocks and sand.
2、Technical parameters of geological drill pipe
No. Diameter (mm) Length (mm) 1 F34 500 ~ 3000 2 F42 500 ~ 3000 3 F50 500 ~ 3000 4 F63.5 500 ~ 3000 5 F73 500 ~ 3000 6 F89 500 ~ 3000 7 F35 500 ~ 3000 8 F42 500 ~ 3000 9 F50 500 ~ 3000 10 F60 500 ~ 3000
3、Common specifications and materials of geological drill pipes:
Generally, there are Ф 42x 760,Ф 42x 800, Ф 42x 1000, Ф 42x 1500, Ф 42x 2000, Ф 42x 2500, Ф 50x 800, Ф 50x 1000, Ф 50x 1500, Ф 50x 2000, Ф 50x 3000, Ф 63.5x 1000, Ф 63.5x 1500, Ф 73 x 1000, Ф 73 x 1500, etc. The model and specification of R780(42MnMo7) drill pipe produced by Yiguang Technology adopts the normalizing and tempering heat treatment process, which has excellent mechanical properties and is suitable for higher-level drilling requirements. You can also customize it according to your own needs.
2.Quality and technology of geological drill pipe
Good materials and processes determine the quality of the product, soWhen choosing geological drill pipe, weFirst of allTo seeitsComposition of raw materials. Beneficiation TechnologyThe production of geological drill pipes, the raw materials used, are from the regular large-scale steel mills at home and abroad, the procurement of high-quality seamless steel pipes, steel pipes used in the production process, are based on the industry.MostFor the approved hot rolling or cold drawing process, the steel pipe production procedures of these steel mills have very strict production process and supervision to ensure that each steel pipe manufactured is of high quality. Beneficial Mining TechnologyDrill pipe processing technology is worth learning, they first through the end of the steel pipe for intermediate frequency heating, hydraulic upsetting, in order to increase the end of the pipe wall thickness, followed by thread processing and appropriate process. During these processes, they will strictly control each step to further ensure that the product'sQuality is worth considering.
