Underground mining drill pipe is one of the important tools in the production process of geological exploration and coal exploration. The downhole mining drill pipe adopts high-quality, high-efficiency, energy-saving, and pollution-free friction welding technology, and the post-weld heat treatment process is studied, and a toughened overall geological drill pipe（extension rod） is obtained.

Welded joint

The comprehensive mechanical performance of the DZ60 geological drilling rig is higher than the value specified in the technical standard for bars and pipes of the DZ60 geological drilling rig.

The role of underground mining drill pipe（extension rod）:

Down-hole mining drill pipe is used to connect the ground equipment of the drilling rig and the drilling and grinding equipment or bottom hole equipment at the bottom of the well.The purpose of the drill pipe（extension rod） is to transport the drilling mud to the drill bit（thread button bits） and raise, lower or rotate the bottom hole drilling tool. The drill pipe must be able to withstand huge internal and external pressures, twisting forces, bending, Flexibility and vibration. In the mining and refining process, the underground mining drill pipe（extension rod） can be reused.

After several processing steps, the original steel pipes and bare pipes are made into underground mining drill pipes. First, through the treatment of the steel pipe thickening step, the outer surface of the smooth pipe is bent inward, and the wall of the steel pipe is thickened. In the next step, the threads will be machined and plated with copper to increase strength.

Then perform non-destructive quality control, and then weld the steel pipe joints. Then, the pipe body will undergo welding heat treatment and welding final treatment to eliminate welding residual pressure. Before painting and packaging the finished underground mining drill pipe, the finished steel pipe should be subjected to some other tests, including

Hardness testing, pressure testing and non-destructive testing.

Features of underground mining drill pipe（extension rod）:

1. The drill pipe for underground mining can be cold drawn once to form a blade without annealing, and has good toughness and durability.

2. The underground mining drill pipe（extension rod） of the pile driver equipment is connected by plug-in screws, which is convenient and quick to disassemble, has good sealing performance, high tensile strength and high pile quality. Good verticality, easy to disassemble and install.

This is the specification:
