Which statement about pipe fittings is true?

• A. They can be flanged, threaded or welded
• B. They must be soldered
• C. They are never used for piping
• D. They are only used with hoses

Answer: (A)

Pipe fittings are the components that connect pipe sections and allow changes in direction, size, or connection to equipment. The statement is true because fittings are designed to use several standard connection methods, with flanged, threaded, and welded being among the most common on ships. Flanged joints provide strong, removable connections ideal for large-bore piping and maintenance access. Threaded fittings are compact and convenient for small-diameter lines or where easy disassembly is needed without welding. Welded fittings form continuous, leak-tight joints suitable for high-pressure and high-temperature sections of marine piping. The other options don’t fit: soldering is not mandatory for all fittings and is typically limited to specific materials or low-pressure, small-diameter copper piping; fittings are used for piping, not exclusively for hoses.
