Pipe fittings are flanged, threaded or welded.

• A. Flanged fittings only
• B. Flanged, threaded or welded
• C. Welded fittings only
• D. Threaded fittings only

Answer: (B)

Joining pipe fittings can be done in several ways. In practice, fittings are connected by flanged, threaded, or welded joints. Flanged joints use bolted flanges with a gasket and are suitable for higher pressures and easier disassembly for maintenance. Threaded joints screw together and are common for smaller-diameter lines, but they’re best for lower pressures and require proper sealing to prevent leaks. Welded joints create a continuous, leak-tight connection with high strength, ideal for demanding service, though they’re permanent once made. Because construction uses all three methods depending on the application, the statement is accurate.
