Carbon steel seamless pipe manufacturing annular parts, can improve material utilization, simplify the manufacturing process, saving time and material processing stations, such as bearing rings, jack sets, is currently widely used to make steel.
Carbon steel seamless pipe or a variety of conventional weapons indispensable material, barrel, barrel would have to make steel. Pipe according to different cross-sectional shapes can be divided into tube and shaped tubes. Because in the perimeter of equal conditions, the largest area of a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the vast majority of pipe is pipe.
the temperature at which the structure and the environment, seamless steel pipe is cold crisp cold easily, so the structure of the work at low temperatures, especially in welded structures, should be used in killed steel has good resistance to low temperature brittle fracture properties. In addition, the open structure of seamless steel pipe prone to aging, harmful media effects seamless steel susceptible to corrosion, fatigue and fracture, should be distinguished selection of different materials.
the thickness of seamless steel pipe, seamless pipe rolling thin more often, rolling compression ratio is small, so a large thickness precision steel strength is not only smaller than large, large thickness seamless steel compression, and ductility, impact toughness and welding performance is poor. Therefore, the large thickness of the welded structure should be used better materials seamless steel tubes.
