In many drilling applications, pipes, casing, and hammers need to be connected ("make up") using specific torque to prevent damage. In addition, drilling companies often want to tighten tools together so that untightening ("break out") is not delayed by stuck or over-tightened/over-torqued tools, which can happen with traditional spinners.
Scorpion Oil Tools manufactures hydraulic tongs that can make up pipes, casing, and hammers/bits at specific torques. Scorpion's hydraulic make up units can help to protect expensive tools as well as prevent down-time when it comes time to break the pipes out. This also allows companies to adhere to pipe and hammer manufacturers' specifications.
