Din 2391c Precision Seamless Steel Tube

Dimensions:

• • Precision Manufacturing: The cold-drawn process ensures high dimensional accuracy and smooth internal and external surfaces.
  • High Strength: The tube is made of high-quality carbon steel that offers exceptional tensile strength and resistance to mechanical stress.
  • Corrosion Resistance: Tubes can be treated for enhanced corrosion resistance, making them suitable for various harsh environments.
  • Seamless Design: The seamless structure ensures better reliability and avoids issues like seam defects which can occur in welded tubes.
  • Surface Finish: Smooth surface finishes, especially after cold drawing, allow for better fluid flow in hydraulic systems, reducing friction and wear.

   

  Surface:

  • Standard: The tube typically comes with a corrosion-resistant oil coating on both inner and outer surfaces to protect against rust during storage and transportation.
  • Optional Surface Treatments: Additional treatments like phosphating, chrome plating, or passivation can be applied depending on specific requirements for anti-corrosion and durability.

   

1. Piercing: A solid steel billet is first pierced to create a hollow tube.
2. Cold Drawing: The tube undergoes cold drawing to achieve precise dimensions and smooth surfaces.
3. Annealing: The tube is annealed to relieve internal stresses created during the drawing process.
4. Surface Treatment: After drawing and annealing, the tube may undergo surface treatments such as phosphating or zinc coating to enhance corrosion resistance.
5. Inspection: The tube is thoroughly inspected for dimensional accuracy, surface quality, and mechanical properties.

Applications

• Hydraulic Systems: Widely used in high-pressure hydraulic systems such as in machinery, construction equipment, and automotive applications.
• Mechanical Engineering: Suitable for mechanical applications where high precision and strength are needed, such as in pumps, compressors, and pressure vessels.
• Automotive: Used in hydraulic braking systems, power steering systems, and fuel systems in vehicles.
• Industrial Machinery: Ideal for use in manufacturing equipment and heavy-duty machines that require high-quality, high-pressure steel tubing.
