Shandong seamless steel pipe knowledge: Small-diameter hot-rolled seamless steel pipes are defined as those with a diameter of 159 mm or less. These small-caliber seamless steel tubes are mainly manufactured through a series of key processes, including billet preparation, heating, piercing, rolling, sizing, cooling, and finishing. During the casting process, imperfections such as bubbles, cracks, and looseness can be eliminated through the high temperature and pressure applied during rolling, resulting in a stronger and more uniform structure.
