ASTM A335 P2 P9 Seamless Alloy Tubes

ASTM A335 /A335M ASME SA335 pipes shall be made by the seamless process and shall be either hot-finished or cold drawn with the finishing treatment.

ASTM A335 /A335M covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.

  • 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.

Materials and Manufacture:

  • 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.

Note:

  • Mill test certificates will be issued according to EN10204.3
  • All tubes shall be supplied as per applicable ASTM A335 /A335M Specification.
