ASTM A530/A530M Pipe

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.
