Which of the following is not a means normally employed to attach flanges to piping?

• A. Welding
• B. Bolting
• C. Integrally forged
• D. Threaded connections

Answer: (C)

Integrally forged connections are not typically utilized as a means of attaching flanges to piping systems. This method involves creating a seamless or solid structure that combines the flange and pipe into a single piece, which is not standard practice for flanged connections. In contrast, welding, bolting, and threaded connections are common methods for attaching flanges to piping. Welding provides a strong, permanent bond, bolting allows for easy assembly and disassembly, and threaded connections can be convenient for smaller applications where flanges may not be feasible. Understanding the typical methods for flange attachment helps reinforce safe and effective practices in piping systems.
