Materials and Manufacture:

  • The Steel shall be killed.
  • The Tubes shall be made by the seamless process and shall be either hot-finished or cold finished, as specified.
  • Heat Treatment – Hot-finished tubes shall be heat treated at a temperature of 1200 °F [650 °C] or higher. Cold- finished tubes shall, after the final cold finishing, be heat treated at a temperature of 1200 °F [650 °C] or higher, or tubing may be furnished in the full-annealed, isothermal annealed, or normalized and tempered condition. If furnished in the normalized and tempered condition, the minimum tempering temperature shall be 1200 °F [650 °C].

Note:

  • Mill test certificates will be issued according to EN10204.3.
  • All tubes shall be supplied as per applicable ASTM A209 /A209M Specification.
