pipe specs/IDs/thicknesses 2

[sagarini]

i would really appreciate some clarification on the differences in these 2 specs: 1) A105N/A516 GR. 60 2) A672 GR. C60/A105. I understand that the materials of consstruction are different but for a given size and schedule, 48" standard schedule for example, are the IDs the same?

thanks

You're mixing apples and oranges and bananas. The materials specification is just that - it specifies the material (apple). The thickness required for internal pressure is a function of the design code (orange). The wall thickness standard is something again different - STD wall thickness is the same regardless of the material (banana).

A 105 and A 516 are carbon steel materials. If ASTM A 672 is carbon steel pipe then ASME B36.10 covers the dimensions. Pipe schedules and dimensions can differ for different materials. For example, ASME B36.19 applies to stainless steel.
