Products Description
Our Advantages
1. High Pressure Resistance
- The 304 hexagonal pipe is seamless hexagonal tubes manufactured through processes such as hot extrusion, cold rolling, and cold drawing, possessing uniform strength and fatigue resistance.
- Through mechanical performance testing, they maintain strength under pressure fluctuations and are suitable for medium and high-pressure systems.
2. Corrosion Resistance
- Our stainless steel hexagonal pipes are made of 304 material, capable of resisting corrosion from atmospheric conditions, water, weak chemicals, and humid environments.
- The pipes undergo rigorous chemical composition testing and intergranular corrosion testing to ensure a long service life in general industrial environments.
3. Excellent Machinability
- The chromium content of the 304 hexagonal pipe allows the material to automatically regain its corrosion resistance after cutting, drilling, or milling.
- Our pipes are pickled and passivated. For chemical and precision machinery applications, passivation treatment can be reapplied after heavy machining.
4. High Dimensional Accuracy
- Our hexagonal pipes are manufactured using precision molds and cold drawing, followed by straightening and rigorous dimensional inspection, ensuring precise geometric shapes and strict tolerances.
- Dimensional inspection reports and MTC test certificates are available to ensure that assembly fit, torque connection, and sealing performance are not affected.
application areas
- Mechanical and fastening: Shafts, bolts, nuts, and other components requiring hexagonal engagement.
- Decorative and architectural: Handrails, furniture, stair railings, and decorative frames.
- Hydraulic and pneumatic fittings: Specialized connectors or actuator components.
- Industrial equipment and machinery: Structural supports, frames, and guide rails in chemical plants, electrical equipment, and light machinery.
- Automotive industry: Drive shafts and couplings, fasteners and assembly components, steering and suspension parts, etc.
