DTH Drill Pipes manufacturers

What is the difference between DTH drill pipe and geological drill pipe?
The most obvious difference is the way of power transmission. When the geological drill pipe is used, it transmits the torque of the drilling rig and drives the drill bit to drill; when the DTH drill pipe is used, it is generally used for connection, and its power generating device is an impactor. , and use wind energy to generate power to drive the drill bit to drill, because the impactor is submerged into the hole and directly connected to the drill bit, so its drill bit is called a down-the-hole drill bit, and the drill pipe is called a DTH drill pipe.

In what scenarios can DTH drill pipe be applied?
DTH drill pipe has been widely used in the drilling of blast holes and non-blast holes in fixed mines such as metallurgy, coal, building materials, and non-ferrous metals, as well as earthwork excavation projects in water conservancy, hydropower, water and land transportation, and municipal construction.

Causes of drill pipe damage
1. Vibration and bending wear. When the drill string reaches the critical speed, the drill pipe vibrates, which often causes bending, excessive wear, rapid damage and fatigue failure of the drill pipe.
2. Tensile damage. It often occurs when the drill sticks during lifting, and the upper drilling tool must not only bear the pressure, but also bear the weight of the drill string to cause damage.
3. Corrosion. The main corrosive agents affecting drilling tool steel are: oxygen, carbon dioxide, hydrogen sulfide, dissolved salts, acids, etc. Factors affecting corrosion rate: low mud pH value (below 9.5), temperature, mud flow rate, etc.
4. The material and thickness of the drill pipe body are not up to standard.
