Precision Round Outer Octagon Inner Hollow Steel Tube

Precision outer circular and inner octagonal hollow steel pipe   Our factory specializes in producing precision outer and inner octagonal hollow steel pipes, which are commonly used composite shaped structural pipes in the fields of industrial machinery, hydraulic equipment, automotive parts, and petroleum machinery. The product adopts the seamless cold drawing process, with a standard circular structure on the outside, high concentricity, strong adaptability, and compatibility with conventional circular mounting bases and bearing assemblies; The interior is a regular octagonal inner hole with symmetrical cross-section and clear edges. It has excellent anti rotation limit, synchronous bite, and anti torsion stability performance, effectively solving common problems such as slip, positioning deviation, and easy loosening under heavy load in ordinary circular tube transmission. The wall thickness of the tube is uniform, the organization is dense, and the strength is stable. The overall…
