Steel plate is formed into seamless pipes through a process called piercing and rolling. In this process, the steel plate is first heated and then pierced to create a hollow tube. The pierced tube is then elongated and shaped using a series of rollers to achieve the desired dimensions and thickness. This seamless pipe manufacturing method ensures a uniform and continuous structure without any welded seams.
Steel plate is formed into seamless pipes through a process called hot rolling. In this process, a steel plate is heated and then passed through a series of rolling mills to gradually reduce its thickness and shape it into a cylindrical form. The edges of the plate are then welded together to create a seamless pipe.
