According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes. According to the material, they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes.

[0003] During the production process and after the production of the completed metal pipe fittings, the pipe fittings need to be transported and moved, and basically manual handling operations are required for the pipe fittings. With the advancement of science and technology, equipment for transporting metal pipe fittings emerges in an endless stream. After searching, a metal pipe material handling device with a publication number of CN110775607A includes a driving component and a lifting component; the driving component includes a rotating device and a telescopic rod, and the rotating device includes a motor, a driving wheel and a driven wheel; the lifting component includes a support plate and a lifting plate, and the lifting plate is slidably arranged on the support plate and locked and fixed by a locking rod, wherein the driving component only has the function of driving the lifting component, and the lifting method adopted by the lifting component for the metal pipe fittings can only grab the pipe fittings, but for the grabbing work of the metal pipe fittings, not only can the handling work not be carried out in large quantities, but also after the pipe fittings are clamped, the irregular placement of the pipe fittings will cause the pipe fittings to fall off during the moving and transportation process. If the fixing strength of the pipe fittings is to be strengthened, the pipe fittings will also be damaged, affecting the quality of transportation. Summary of the invention
