Which standard provides dimensions for carbon steel pipes?

Which standard provides dimensions for carbon steel pipes?

• A. ASME B36.19
• B. ASME B36.10
• C. ASME B31.3
• D. API 5L

Answer: (B)

ASME B36.10 is the reference for standard welded and seamless wrought steel pipe dimensions, including carbon steel. It defines the outside diameter for each nominal size and the corresponding wall thickness or schedule, which is exactly what you need when you’re looking up how big a carbon steel pipe is. The metric version is B36.10M, used for metric units. The other standards serve different purposes. ASME B36.19 covers stainless steel pipe dimensions, so it isn’t the right source for carbon steel. ASME B31.3 is a design and integrity standard for process piping, not a catalog of pipe sizes. API 5L defines line pipe specifications for offshore and onshore oil/gas pipelines, including grades and tolerances, but not the general dimension tables used for carbon steel pipes in everyday piping practice. So for carbon steel pipe dimensions, the go-to standard is ASME B36.10.
