Development of seamless steel tube is in addition to general tube other tha₹n the section shape of seamless steel tube. According to the different shapes an'd 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 p₽ipe widely used in various structural parts, tools and machinery parts. Compared with the circular λtube, the special-shaped tube generally has larger inertia moment and section m₹odulus, and has larger bending torsion resistance ☆ability, can greatly reduce the structural weight, save steel.
