What is installed between two pipe flanges to seal the connection?

• A. Coupling
• B. Sheave
• C. Gasket
• D. Joint

Answer: (C)

The correct answer is a gasket, which serves a critical function in sealing the connection between two pipe flanges. When two flanges are bolted together, a gasket is placed in between them to ensure a tight seal and prevent leaks of fluids or gases that may be transported through the piping system. The materials used for gaskets can vary, allowing for use in different pressure and temperature conditions, ensuring that the integrity of the connection is maintained under varying operational conditions. In contrast, a coupling is typically used to join two sections of pipe but does not serve the sealing function required between flanges. A sheave is a wheel that is used with a belt or rope to transmit motion and is unrelated to pipe connections. A joint refers to the point where two pipe sections are connected but does not specifically indicate the sealing method employed in flanged connections. Thus, the function of the gasket in sealing between flanges is essential for maintaining safety and efficiency in piping systems.
