Product Description
The heat treatment of steel for down-the-hole drill pipes is processed using an integrated vacuum furnace. All thread processing uses professional CNC machining. All threads are equipped with thread gauges that meet international standards. The inner thickening process is used at the end of the rod body and the tempering treatment is carried out after friction welding. Therefore, the quality of the processed drill pipe is stable and reliable, and the service cycle is greatly extended.

In terms of structural design, the rod body adopts a triangular pyramid structure, which reflects the characteristics of energy saving and high efficiency in production and use.
A joint pipe is a connection tool between a pipe and a pipe, and a connection point between a component and a pipe that can be disassembled and assembled.It plays an indispensable and important role in pipe fittings
Blast furnace opening steel has a high impact frequency, high rotation and high forward and reverse strength, and the drill rod of the blast furnace opening machine can withstand the high-frequency impact of the rock drill and the difficult work of strong torsion.
