Precision special-shaped seamless steel pipe is a general term for seamless steel pipes with other cross-sectional shapes except round pipes. According to the different cross-sectional shapes and sizes of steel pipes, they can be divided into equal wall thickness precision special-shaped seamless steel pipes (codenamed D), unequal wall thickness precision special-shaped seamless steel pipes (codenamed BD), and variable diameter precision special-shaped seamless steel pipes (codenamed BJ). Precision special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
