ASME SA213 T11 tube Quality control

  • 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 – Ferritic Alloy and Ferritic Stainless Steels – The ferritic alloy and ferritic stainless steels shall be reheated for heat treatment in accordance with the requirements of Standard. Heat treatment shall be carried out separately and in addition to heating for hot forming.
  • Flattening Test—One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot
  • Flaring Test—One flaring test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot
  • Hydrostatic or Nondestructive Electric Test—Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.

Note:

  • Mill test certificates will be issued according to EN10204.3
  • All tubes shall be supplied as per applicable ASME SA213M / SA213 Specification

Differences between ASTM A213 T11 and ASME SA213 T11

ASTM A213 T11 and ASME SA213 T11 are essentially equivalent specifications for seamless ferritic alloy steel tubes. Both of the standards are used for high-temperature applications such as boilers, superheaters, and heat exchangers.

ASTM A213 T11: Published by the American Society for Testing and Materials (ASTM).

ASME SA213 T11: Published by the American Society of Mechanical Engineers (ASME), primarily for use in boiler and pressure vessel codes.Which requires additional certification for compliance with ASME Boiler and Pressure Vessel Code (BPVC)..

Chemical and mechanical properties are the same for both ASTM A213 T11 and ASME SA213 T11.

The only difference between those 2 standards is that  ASME SA213 being tailored for pressure vessel code applications.

The A213 T11 tube is a reliable solution for high-temperature and high-pressure applications. Its excellent balance of strength, corrosion resistance, and cost-effectiveness makes it a preferred material for boilers, superheaters, and heat exchangers across various industries.
