Product Description
The steel used for drilling pipes for wells is a steel pipe used by geological departments for core drilling. It has high strength, good elasticity, is not easy to bend, and is easy to connect. It can be used in conjunction with various coal-fired electric drills or tunnel drilling rigs.The slag discharge is smooth and the accumulation of rock slag is reduced.
The process of making finished products from steel for drilling pipes for wells：
Iron ore is selected from steelmaking, continuous casting (mold casting), pipe rolling, pipe end thickening, pipe body heat treatment, tool joint manufacturing, friction butt welding, weld heat treatment to the finished drill pipe.

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.
