    A213 T11 ≥415 ≥205 30 ≤179


    Tests and Inspection

    Hardness Requirementx:
    Brinell, Vickers, or Rockwell hardness tests shall be made on specimens from two tubes from each lot. 

     
    Flattening Text—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 Text—One flaring test shall be made on speci- mens from each end of one finished tube, not the one used for the flattening test, from each lot.
     
    Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] in inside diameter or thinner than 0.015 in. [0.4 mm] in thickness.
     
     
     
    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.
     
    Forming Operations
    Tubes, when inserted in a boiler or tube sheet, shall stand expanding and beading without showing cracks or flaws. Superheater tubes when properly manipulated shall stand all forging, welding, and bending operations necessary for appli- cation without developing defects.
