Bucking Units vs. Breakout Machines: Choosing the Right Tool for Pipe Torque Applications
What Are Bucking Units and How Do They Work? Bucking units are powerful torque devices for tightening or loosening threaded connections on oilfield tubulars. Before they leave the shop or rig to go to the field, these tools are typically set up in shops or rigs to assemble tool joints, drill pipes, or collars, or even to put together MWD or LWD tool strings. Their hydraulic clamping tools are highly precise, and repeated use is important for safe, reliable well performance. Breakout Machines: Key Functions and Field Use The main purpose of breakout machines is to release pipe connections that are too tight, jammed, or over-torqued. They are useful in the field when you need to rapidly and safely break down tools and pipelines. They are also often used during disassembly or maintenance. Breakout machines are sometimes available in portable forms, which makes them an excellent alternative for jobs that need to be done on-site. Differences in Torque Control and Speed Torque con...
