External hexagonal, internal circular steel tube

What materials are available for hexagonal steel pipes?

Hexagonal steel pipes, also known as non-standard steel pipes, include octagonal pipes, diamond-shaped pipes, and elliptical pipes, among others. They are economic section steel pipes, encompassing non-circular cross-sections, equal wall thicknesses, variable wall thicknesses, varying diameters and wall thicknesses along the length, symmetrical and asymmetrical cross-sections, such as square, rectangular, conical, trapezoidal, and spiral shapes. Non-standard steel pipes are better suited to the specific requirements of usage conditions, saving metal and increasing the labor productivity of component manufacturing. They are widely used in aviation, automotive, shipbuilding, mining machinery, agricultural machinery, construction, light industry and textiles, and boiler manufacturing. Methods of producing non-standard pipes include cold drawing, electric welding, extrusion, and hot rolling, with cold drawing being the most widely applied method. Hexagonal steel, also known as hexagonal bar, is a type of structural steel with a cross-section in the shape of a regular hexagon. The nominal size is specified by the length of the opposite sides, S. Hexagonal steel can be assembled into various different load-bearing components according to structural needs and can also serve as connecting elements between components. It is widely used in various architectural and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves.

Non-standard pipes are typically differentiated by their cross-section and overall shape, and generally include: elliptical non-standard steel pipes, triangular non-standard steel pipes, hexagonal non-standard steel pipes, rhombic non-standard steel pipes, stainless steel patterned pipes, stainless steel U-shaped pipes, D-shaped pipes, stainless steel elbow pipes, S-shaped bend pipes, octagonal non-standard steel pipes, semi-circular steel rounds, unequal edge hexagonal non-standard steel pipes, five-petaled plum blossom-shaped non-standard steel pipes, double-convex non-standard steel pipes, double-concave non-standard steel pipes, stainless steel water trap elbows, melon-shaped non-standard steel pipes, conical non-standard steel pipes, corrugated non-standard steel pipes, and more.

Hexagonal steel pipe application material classification: 20#, 45#, 16Mn, etc., with different materials for various uses. Hexagonal steel pipes are steel pipes with an external hexagonal shape. They are a type of special-shaped steel pipe. They are commonly used in the processing of nuts, mechanical components, etc. Hollow hexagonal bars are a general term for steel pipes with an external hexagonal and internal circular cross-section, including welded special-shaped pipes and seamless special-shaped pipes. Due to the material, they can be categorized as ordinary carbon steel special-shaped pipes and stainless steel hexagonal tubes.
