  We have adopted advanced production equipment and technologies to manufacture our carbon steel seamless pipe  fitting, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.

  Scope

  ASTM A53 seamless steel tube covers seamless carbon steel nominal wall pipe for high-temperature service. Suitable for bending, flanging and similar forming operations.

  NPS 1-1/2" and under may be either hot finished or cold drawn. NPS 2" and larger shall be hot finished unless otherwise specified.

  Process

  Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining.

  Steel cast in ingots or strand cast is permissible.

  Hot-finished pipe need not be heat treated.

  Cold-drawn pipe shall be heat treated after the final cold draw pass.
