Product introduction | ||||
Special-shaped seamless steel tube is the general name of seamless steel tube with other cross-sectional shapes except circular tube. According to the different cross-sectional shapes and sizes of steel pipes, it can be divided into special-shaped seamless steel pipes with equal wall thickness (code D), special-shaped seamless steel pipes with unequal wall thickness (code BD) and special-shaped seamless steel pipes with variable diameter (code BJ). | ||||
Properties of special-shaped steel pipes; | 1. Performance index of special-shaped steel pipe-plasticity 2. Performance index of special-shaped steel pipe-hardness 3.
