Product Description

DTH drill pipes are widely used in mines, water wells, geothermal, petroleum and other types of DTH rigs. High quality carbon steel ensures the close combination of friction welding process and joint. According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice versa.
