NJ series twisting machine
NJ series hydraulic screwing machine is a kind of threaded coupling loading and unloading machine. It adopts high reliability design and is resistant to difficult field conditions. It is suitable for oil and casing factory coupling and oil field downhole pump, downhole tool, oil pipe and sleeve. The manufacture, assembly and repair of pipes and other threaded couplings have the following characteristics:
◆ Simple appearance and beautiful appearance;
◆ The clamp head adopts the planetary claw clamping mechanism, and no parts need to be replaced in the applicable range.
◆ The main back clamp has a small spacing and can be used for ultra short and short sections and tools;
◆ The back clamp is equipped with a hydraulic walking mechanism that can move with the workpiece;
◆ Optional torque control system. The installation torque automatic control system works better.
