Frequently Asked Questions
What is drill pipe?
Drill pipe is a round metal rod manufactured from tool steel, ground and polished to tight tolerances. Typically supplied unhardened for easy machining, making it ideal for specialized tooling applications.
What are the two main functions of drill pipe?
Torque Transmission: Transmits drilling torque over extended distances from surface equipment to the drill bit.
Fluid Circulation: Serves as a conduit for drilling fluid (mud) to cool the drill bit, transport cuttings, and maintain wellbore pressure.
Fluid Circulation: Serves as a conduit for drilling fluid (mud) to cool the drill bit, transport cuttings, and maintain wellbore pressure.
How are drill rods manufactured?
Drill pipe production involves cutting pins and threads directly into steel pipe, creating a robust one-piece structure used in conventional wireline drilling systems.
