A. Diameter tolerance is not applicable to normalized and tempered or quenched and tempered conditions. B. The common range of sizes of hot finished tubes is 11⁄2 in. (38.1 mm) to 103⁄4 in. (273.0 mm) outside diameter with wall thickness at least 3 % or more of outside diameter, but not less than 0.095 in. (2.41 mm). C. Larger sizes are available, consult manufacturer for sizes and tolerances.
