| 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. Performance index of special-shaped steel pipe-fatigue 4. Performance index of special-shaped steel pipe-impact toughness 5. Performance index of special-shaped steel pipe-strength " | |||
| The purpose of special-shaped steel pipe: | Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. | |||
| Special-shaped steel pipes are divided into: | Special-shaped steel pipes such as external hexagonal internal circular steel pipe, external hexagonal steel pipe, internal and external hexagonal steel pipe, flat oval steel pipe, oval steel pipe, triangular pipe, L-shaped steel pipe, octagonal pipe, mushroom-shaped pipe, bread-shaped pipe, D-shaped pipe, concave pipe, convex pipe, umbrella-shaped pipe, P-shaped pipe and ingot-shaped pipe are produced according to users' needs. | |||
