Special-shaped pipes are seamless steel pipes that are cold drawn into various special-shaped pipes. Special-shaped pipes are generally distinguished according to the broken section, and can be divided into seamless steel pipe special-shaped pipes, aluminum alloy special-shaped pipes, and plastic special-shaped pipes according to the material. Shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the different shape and size of the steel pipe section, it can be divided into equal-wall thickness special-shaped seamless steel pipe (code D), unequal wall thickness special-shaped seamless steel pipe (code BD), variable diameter special-shaped seamless steel pipe (code BJ).
