Product Description
[Application scope]
It is mainly used for various types of drilling operations such as gas drainage (mining) drilling, water drainage holes, grouting holes, etc. with good underground formation conditions in coal mines. It can also be used for drilling construction in mining, geology, hydropower and other industries, with high drill pipe strength. It is suitable for both conventional drilling and percussive rotary drilling. The high-pressure sealed drill pipe can be used in the hydraulic coal cutting process, and the high-tenacity drill pipe can be used for directional long drilling and reaming construction.
