Which standard is for wrought carbon steel piping fittings?

Which standard is for wrought carbon steel piping fittings?

• A. ASME B16.4
• B. Nonmetallic Pipe
• C. ASTM A 234
• D. Gauge Pressure

Answer: (C)

ASTM A234 is the standard that defines piping fittings made from wrought carbon steel and alloy steels, including elbows, tees, reducers, caps, and similar parts. It specifies material requirements, dimensions, tolerances, mechanical properties, and testing to ensure these fittings will interchange with standard pipe and operate reliably in sprinkler system service. This makes it the go-to standard for carbon steel fittings. ASME B16.4 covers flanges and flange fittings, which is related but not the general standard for all wrought carbon steel fittings. Nonmetallic Pipe isn’t a standard for metal fittings, and Gauge Pressure is a measurement, not a standard for fittings.
