Product Description

Shaped seamless steel tube is a general term for those seamless steel tubes in other cross-sectional shapes, except the circular tube.

According to the different shapes and sizes of the cross-section, shaped seamless steel tube also can be divided into equal wall thickness shaped seamless steel (code D), unequal wall thickness shaped seamless steel (code BD) and variable diameter shaped seamless steel (code BJ).

Shaped seamless steel tube is widely used for various structures, tools and mechanical components. Compared with circular tube, shaped seamless steel generally has a larger moment of inertia and section modulus, greater anti-bending and anti-torque ability, which can greatly reduce the structural weight to save steel.

Generally shaped tube is distinguished based on broken section. According to the materials, shaped seamless steel tube also can be divided into seamless shaped tube, aluminum alloy shaped tube and plastic shaped tube. Here we mainly introduce the steel shaped tube.

Steel shaped tube can be divided into oval steel shaped tube, triangular steel shaped tube, hexagonal steel shaped tube, diamond steel shaped tube, octagonal steel shaped tube, semi-circular steel shaped tube, inequilateral hexagonal steel shaped tube, five plum steel shaped tube, double convex steel shaped tube, double concave steel shaped tube, oval steel shaped tube, cone steel shaped tube and corrugated steel shaped tube.

Shaped tube is divided into square shaped tube, rectangular shaped tube, welded shaped tube and spiral welded pipe.
