Steel pipe with a pin at one end and steel pipe with a box at the other end make up the majority of DTH drill pipe. The drill pipe's function is to transmit the drill bit's rotational torque and thrust to the downhole drill. The DTH drill Bit and hammer can be controlled together by connecting a DTH drill pipe. For different uses, different diameters are needed. In essence, smaller DTH tools need smaller DTH drill pipes and vice versa. We often offer 50mm, 60mm, 76mm, 89mm, and so forth. The common threads on DTH drill pipes are standard API connections such as the 23/8" API REG thread, the 31/2" API REG thread, or the API IF thread. All DTH drill pipes are friction welded.

 

What are DTH drill pipes used for?

DTH (Down-The-Hole) drill pipes can be used in various engineering conditions and industries. Here are some examples of engineering conditions where DTH drill pipes are commonly employed:

 

Mining Exploration: DTH drill pipes are extensively used in mining exploration. They are employed for extracting different types of minerals, such as metal ores, coal, and gemstones. DTH drill pipes deliver compressed air and rotational power to drive the drill bit, enabling rock penetration and fragmentation underground.

 

Foundation Engineering: In foundation engineering, DTH drill pipes are commonly used for pile driving and drilling. They are employed for drilling deep foundation pits, bridge piers, building foundations, as well as for the installation of piles and support rods.

 

Water Well Drilling: DTH drill pipes play a vital role in water well drilling. They are used for drilling water supply wells, geothermal wells, or monitoring wells. DTH drill pipes enable fast and efficient penetration through underground rock formations to access groundwater resources or for groundwater monitoring purposes.

 

Geotechnical Engineering: DTH drill pipes are utilized for soil and rock sampling and testing in geotechnical engineering. They can be used for soil exploration, rock mechanics testing, and geological surveys.

 

Environmental Site Assessment: Environmental site assessment involves investigating and monitoring soil and groundwater contamination. DTH drill pipes can be used for drilling monitoring wells to collect soil and groundwater samples for analysis and testing.

 

Geological Exploration: DTH drill pipes find extensive use in geological exploration. They are employed for prospecting mineral deposits, oil and gas reservoirs, and underground geological structures. DTH drill pipes can penetrate deep into complex geological formations, allowing for geological information and sample collection.

 

Characteristics of DTH drill pipes

The drill bit is used to raise, lower, or rotate the bottom hole device while drilling mud is transferred to the drill bit via the drill pipe. The DTH drill pipes need to be capable of withstanding high levels of internal and external pressure, as well as deformation, bending, and vibration. In the process of extracting and refining oil and gas, the DTH drill pipes may be utilized more than once. The DTH drill pipes are created by processing both the thin steel pipe and the light steel pipe. The outer surface of the light pipe is first bent inward during the thickening of the steel pipe procedure to thicken the pipe wall. Second, copper's strength can be increased by threading and plating. The pipe is then welded after a non-destructive quality control test is completed. To remove welding residual pressure, the pipe will then undergo welding heat treatment and final welding treatment. Other tests, such as hardness, pressure, and non-destructive testing, are carried out on the final pipeline before it is painted and packaged. High-quality materials are used to construct the DTH drill pipes, and it has undergone spectroscopic, impact, and tensile testing. Nitrogen is used to treat the surface. It is also simpler to handle because of the robust threads.
