The invention provides automatic steel tube strapping equipment, and relates to the technical field of steel tube strapping. The automatic steel tube strapping equipment comprises a transporting device for transporting steel tubes, supporting devices for supporting the steel tubes, a strapping device arranged above the transporting device and a control device; the control device is connected withthe transporting device, the supporting devices and the strapping device; and the long axes of the steel tubes are parallel to the moving direction of the strapping device, and the movement directionof the strapping device is perpendicular to the transporting direction of the transporting device. According to the automatic steel tube strapping equipment, the movable strapping device is adopted tomove in the long axis directions of the steel tubes so that the steel tubes which are stacked in a certain shape can be strapped for many times in the length direction under the state of no movement,the phenomena that the steel tubes fall off in the strapping process and strapping is not tight or even bales off due to the fact the stacked steel tubes are moved during traditional operation are avoided, the strapping quality of the steel tubes is ensured, and the automatic steel tube strapping equipment has the good using effect and wide promotional value.
