The coupling screwing machine is a device for screwing the coupling to the pipe body according to the standard when the oil pipe or casing is produced. It is mainly composed of a host responsible for screwing, a console for controlling and displaying data, and a hydraulic station.
In automated production lines, there may also be coupling pre-screwers, hoppers and traverse devices, and so on.
Classified by operation
The manually operated coupling screwing machine is mainly used to repair single-piece small-volume production oil casings, which are less efficient.
The automatic operation of the coupling screwing machine is mainly applied to the oil casing production line, and it can realize efficient production with the manual coupling pre-screwing or the coupling pre-twisting machine.
