Mechanical property requirements do not apply to tubing smaller than 1/8'' (3.2mm) in inside diameter or thinner than 0.015'' (0.4mm) in thickness
Hardness Requirements:
Brinell, Vickers or Rockwell hardness tests shall be made on specimens frrom each lot.
Flattening Test:
One flattening test shall be made on specimens from each end of one finished tube, not the one used for 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 flattening test, from each lot
Surface Condition:
Ferritic alloy cold-finished steel tubes shall be free of scale and suitable for inspection. A slight amount of oxidation is not considered scacel.
Ferritic alloy hot-finished steel tubes shall be free of loose scale and suitable for inspection
Stainless steel tubes shall be pickled free of scale. When bright annealing is used, pickling is not necessary.
Any special finish requirement shall be subject to agreement between the customer and our production teams.
