What type of fittings would typically be used to connect two pipes at a right angle?

• A. Couplings
• B. Elbows
• C. Tees
• D. Flanges

Answer: (B)

Elbows are specifically designed to connect two pipes at a right angle, allowing for directional changes in piping systems. They come in various angles, with the standard elbow being a 90-degree turn, which is the most common for creating right-angle connections. This design facilitates the efficient routing of fluids and gases in a piping system without significant disruptions to flow.

Other types of fittings have different functions: couplings are typically used for connecting two pipes in a straight line; tees are used to create branching connections in a system; and flanges serve as a method for joining pipes or components by bolting them together. Therefore, the use of elbows for right-angle connections makes them the ideal choice in piping applications where a turn is necessary.
