Introduction to the structure of drill pipe for rock drilling jumbo

Date: Feb. 28, 2024

The structure of drill pipe for rock drilling jumbo typically consists of three main parts: the pipe body, the connection, and the tool joint.

1. Pipe body: The pipe body is the main component of the drill pipe and is typically made of high-strength steel to withstand the harsh drilling environment. The pipe body is also designed to resist abrasion, bending, and torsional loads.

2. Connection: The connection is the part of the drill pipe that connects one pipe to another. It is usually threaded, so that it can be easily screwed onto and off the drill rig. The connection is also designed to transfer the maximum amount of torque and tension from the drill rig to the pipe body.

3. Tool joint: The tool joint is the end of the drill pipe that connects to the drilling bit. It is designed to transfer the maximum amount of torque and tension from the drill rig to the bit, while also allowing the bit to be easily changed.

Overall, the structure of drill pipe for rock drilling jumbo is designed to withstand extreme stress and strain while drilling through hard rock formations. The pipe body, connection, and tool joint all play important roles in ensuring the drill pipe can effectively transmit the power needed to create boreholes.
