Hydrostatic or Nondestructive Electric Test
Each tube will be subjected to the nondestructive electric test or the hydrostatic test.
Tests
(1)Tension test——One tension test shall be made on a specimen from one tube for lots of not more than 50 tubes. Tension tests shall be made on specimens from two tubes for lots of more than 50 tubes.
(2)Hardness Requirements—— Brinell, Vickers, or Rockwell hardness tests shall be made on specimens from two tubes from each lot.
(3)Flattening Test——One flattening test shall be made on specimens from each end of one finished tube.
(4)Flaring Test——One flaring test shall be made on specimens from each end of one finished tube.
Surface Condition
ASTM A213 T11 Ferritic alloy cold-finished steel tubes are free of scale and suitable for inspection.
ASTM A213 T11 Ferritic alloy hot-finished steel tubes are free of loose scale and suitable for inspection.
