Which standard is the specification for welded and seamless wrought steel pipe?

• A. ASME A17.1
• B. ANSI B36.10M
• C. ASME B16.1
• D. ASME B16.5

Answer: (B)

Understanding pipe sizing standards is essential because they ensure that pipe dimensions match fittings, joints, and system components used in sprinkler installations. The standard that specifies welded and seamless wrought steel pipe dimensions—outside diameter, wall thickness, and tolerances—is ANSI B36.10M. This standard provides the common reference for sizing and ensures compatibility across pipes and fittings used in low-rise sprinkler systems. The other options relate to different things. One is an elevator safety code, not pipe dimensions. Another covers cast iron pipe flanges and flanges, which is a different material and application. The remaining one concerns pipe flanges and fittings but is not the standard for the pipe itself. Therefore, ANSI B36.10M is the correct specification for welded and seamless wrought steel pipe.
