Development of seamless steel tube is in addition to general tube other than the section shape of seamless steel tube. According to the different shapes and sizes of steel pipe section can be divided into equal wall thickness special-shaped seamless steel pipe (code named D), unequal wall thickness special-shaped seamless steel pipe (code named BD), variable diameter special-shaped seamless steel pipe (code named BJ). Shaped seamless steel pipe widely used in various structural parts, tools and machinery parts. Compared with the circular tube, the special-shaped tube generally has larger inertia moment and section modulus, and has larger bending torsion resistance ability, can greatly reduce the structural weight, save steel.
