Roughness: Ra ≤0.8


Test

  • The tubes shall have a hardness test, it is not exceeding 72HRB.
  • One flattening test shall be made on specimens from each of two tubes from each lot or fraction thereof.
  • One flaring test shall be made on specimens from each of two tubes from each lot or fraction thereof.
  • When specified as a substitute for the flaring test, for tubes having a wall thickness (actual mean wall) less than 10% of the outside diameter, one test shall be made on specimens from each of two tubes other than specified above, the flange test shall not be required.
  • Rockwell hardness tests shall be made on specimens from two tubes from each lot.(when the final heat treatment is in a continuous furnace, a lot shall include all tubes of the same size and heat, heat treated in the same furnace at the same temperature, time at heat, and furnace speed)
  • Each tube shall be subjected to the hydrostatic test, or, instead of this test, a nondestructive electric test may be used when specified by the clients.
