Octagonal Outer Round Inner Steel Tube: Composite Structure for Special Assembly

The Octagonal Outer Round Inner Steel Tube adopts a unique composite structural design with an octagonal outer profile and a round inner hole, perfectly solving the assembly matching problem of special mechanical parts. The outer octagonal structure provides excellent anti-slip and anti-rotation positioning effects, avoiding rotation and displacement during equipment operation. The smooth round inner hole ensures precise matching with cylindrical shafts and hydraulic components, realizing dual advantages of stable positioning and flexible transmission. This composite special-shaped tube is widely used in special automation equipment, hydraulic power mechanisms and customized mechanical structural parts, filling the market gap of single-structure steel pipes.

Special Shaped Octagonal Steel Tubing: Customized Industrial Special-Section Tubing

Special Shaped Octagonal Steel Tubing is a customized industrial profile developed for diverse special working conditions. Different from standard octagonal pipes, it supports flexible adjustment of outer diameter, wall thickness and structural radian according to customer engineering needs. Adopting integral cold-drawn seamless forming technology, the product has no welding seams, uniform wall thickness and stable structural performance. It has strong bending resistance and pressure resistance, suitable for non-standard mechanical equipment frames, special engineering supports and customized transmission structural parts, meeting the personalized structural design needs of various industrial projects.

Hexagonal Outer Round Bore Steel Pipe: Dual-Structure Precision Matching Pipe

The Hexagonal Outer Round Bore Steel Pipe is another core composite special-shaped tube of the factory, featuring a hexagonal outer shape and a standard round inner bore. The outer hexagonal structure can realize fast positioning and fixed installation, effectively improving assembly efficiency and structural stability of equipment. The standard round inner hole ensures high-precision matching with standard cylindrical accessories, which is convenient for later installation and maintenance. This composite steel pipe integrates the advantages of hexagonal positioning and round pipe transmission, and is widely used in precision machine tools, mechanical fixtures, transmission shafts and automated production equipment.

Hexagonal Seamless Hollow Steel Pipe: Stable & High-Purity Seamless Tubing

The Hexagonal seamless hollow steel pipe is manufactured through one-piece seamless cold-drawn process, with no welding joints or stress concentration points on the pipe body. The hollow lightweight design reduces the overall weight of equipment while ensuring structural strength. The product features accurate dimensional tolerance, smooth internal and external surfaces and excellent processability, which can be directly used for cutting, drilling, bending and other secondary processing. It is a basic high-quality material for mass production of precision mechanical accessories and industrial equipment frames.

Octagonal Structural Profile Tubing: High-Stability Industrial Profile

Octagonal structural profile tubing relies on the symmetrical octagonal geometric structure to achieve uniform stress dispersion, with better structural stability and load-bearing capacity than conventional profiles. It can withstand long-term static pressure and dynamic alternating load, and is not easy to deform or damage. With diverse standard specifications and customizable sizes, this octagonal profile tubing is suitable for industrial equipment supports, mechanical base frames, engineering trusses and other scenarios, providing stable structural support for industrial production.

Precision Hexagonal Mechanical Tube: High-Accuracy Transmission Accessories

Tailored for high-precision mechanical transmission scenarios, the Precision hexagonal mechanical tube undergoes multiple fine cold drawing and calibration processes to achieve ultra-high dimensional accuracy and straightness. The product has low surface roughness and good fitting performance, which can realize gapless matching with precision mechanical parts. It operates stably at high speed without jitter or deformation, effectively improving the operating accuracy and service life of automation equipment, and is widely used in precision instruments, automated machinery and transmission systems.

Anti-torsion Octagonal Shaped Pipe: Excellent Fatigue & Torsion Resistance

Aiming at equipment working conditions with frequent torsion and reciprocating operation, the Anti-torsion octagonal shaped pipe is structurally optimized for torsion resistance. The symmetrical octagonal section can effectively disperse torsional stress, resist long-term alternating torsion and mechanical fatigue, and avoid pipe body distortion and fracture. It has far better anti-torsion performance than ordinary round pipes and square pipes, and is an ideal core component for transmission shafts, rotary joints, hydraulic equipment and frequently operated mechanical parts.

Alloy Steel Hexagonal Octagonal Section Tube: High-Strength & Durable Alloy Tubing

Made of high-quality alloy steel raw materials, the Alloy steel hexagonal octagonal section tube has higher strength, hardness, wear resistance and corrosion resistance than ordinary carbon steel tubes. After heat treatment and precision forming, the product maintains stable mechanical properties in high-load, high-pressure and complex working environments. It is suitable for heavy-duty machinery, mining equipment, engineering hydraulic systems and other harsh industrial scenarios, realizing long-term stable operation and reducing equipment maintenance costs.
