Other dimensions:  Nominal Pipe Size 1/2 - 4

NPS = Nominal Pipe Size   O.D. = Outside Diameter   WT = Walltickness   KG/M = Kilogram per meter.
Dimensions are in millimeters unless otherwise indicated.
Weights are in kilograms p/meter and approximately given.

Dimensional Tolerances for Seamless and Welded Pipes ASTM A530/A530M

Nominal pipe size up to 4 = ± 0.79 mm | 5 thru 8 = + 1.58 mm / - 0.79 mm 10 thru 18 = + 2.37 mm / - 0.79 mm | 20 thru 24 = + 3.18 mm / - 0.79 mm
Wall Thickness All Diameters = - 12.5% + tolerance not specified	Length + 6.40 mm / - 0 mm	Weight Weight = + 10% / - 1.5%

Dimensions and Dimensional Tolerances

Units of Measure
American pipe standards use imperial and metric (SI) units for measurement. It is important not to combine the use of these units since rounding of dimensions has resulted in an incompatibility between some values.

Dimensions
Standard dimensions for welded and seamless wrought steel pipe for high or low temperatures and pressures are described in ASME B36.10M. Standard dimensions for welded and seamless wrought stainless steel pipe are described in ASME B36.19M. The suffix "S" in the Schedule Number is used to differentiate B36.19M pipe from B36.10M pipe. ASME B36.10M includes other pipe thicknesses which are also commercially available with stainless steel material.

Dimensional tolerances
The basic permissible variations, including pipe length and straightness requirements, are defined in ASTM A530/A530M, this standard being referenced by all ASTM pipe standards.
