What is a Seamless Carbon Steel Tube?

A seamless carbon steel tube is a tubular product manufactured without a welded seam. It is created by piercing solid steel billets and rolling them into a hollow structure. Unlike welded tubes, seamless tubes have a uniform structure and no weak points, making them ideal for high-pressure and high-temperature applications.

Key Features:

  • High Strength: Capable of withstanding extreme pressure and load.

  • Uniform Structure: No seam or weld joint ensures reliability.

  • Versatility: Used in various industries, from oil & gas to construction.

  • Cost-Effective: Durable and long-lasting with minimal maintenance.

Manufacturing Process

  1. Billet Selection: High-quality carbon steel billets sourced from trusted mills.

  2. Heating & Piercing: Billets are heated and pierced to form hollow shells.

  3. Hot Rolling: The pierced billet is elongated and rolled into tubular form.

  4. Cold Drawing (if required): Achieves precise dimensions and smoother finish.

  5. Heat Treatment: Enhances toughness, hardness, and mechanical properties.

  6. Pickling & Surface Finishing: Removes scale and ensures a clean finish.

  7. Inspection & Testing: Every tube undergoes dimensional and quality checks.

Applications
