In pipe fitting, what is typically used to join pipes at an angle?

1. Elbow fitting

2. Tee fitting

3. Reducer fitting

4. Cap fitting

The correct answer is: Elbow fitting

In pipe fitting, elbow fittings are specifically designed to connect two pipes at an angle, typically at 45 degrees or 90 degrees. This allows for changes in direction in the piping system, which is essential for routing piping through various spaces or around obstacles. The curvature of the elbow fitting facilitates a smooth flow of fluids, reducing turbulence and potential pressure drops. In contrast, tee fittings are used to create branches in the piping system, allowing the flow to split into two separate directions from a single line. Reducer fittings are employed to connect pipes of different diameters, enabling transitions in size. Cap fittings are designed to close the end of a pipe, sealing it off entirely. Each of these fittings serves its distinct purpose in plumbing and piping systems, but for joining pipes at an angle, the elbow fitting is the appropriate choice.
