mill tolerance of pipe

Tolerances | Industrial Tube and Steel Corporation

Round bars are made with sufficient stock on the outside diameter to guarantee clean-up at the nominal dimensions. Stock allowance is a function of the bar diameter. Example: 3.00" + 0.118" = 3.118" tolerance is +/- 0.030" Max size = 3.148 Min size = 3.088. A 3.000" bar is guaranteed to finish at 3.000".
