Which standard defines the dimensions for welded and seamless pipe?

Which standard defines the dimensions for welded and seamless pipe?

• A. ANSI B16.5
• B. ANSI B36.14
• C. ANSI B36.10
• D. ASME Section II

Answer: (C)

The main idea is knowing which standard publishes the actual outside diameters and wall-thickness-related dimensions used to fabricate pipe. ANSI B36.10 defines the dimensions for welded and seamless wrought steel pipe, listing standard sizes, outside diameters, wall thicknesses, and related schedule information used across carbon steel and alloy piping. This makes it the go-to reference for general welded and seamless pipe dimensions. ANSI B36.14 focuses on stainless steel pipe sizes, which is a subset rather than the general welded/seamless pipe dimension standard. ANSI B16.5 covers flanges and fittings, not the pipe dimensions themselves, and ASME Section II is about material specifications, not geometry.
