What kind of fittings are used to connect pipes at angles without causing sharp turns?

Elbows are the correct choice for connecting pipes at angles while minimizing sharp turns. They are designed specifically to create a bend in the piping system, typically available in various angles such as 90 degrees or 45 degrees. This allows for a smooth transition from one pipe to another, preserving the flow of fluid and minimizing turbulence and pressure loss that can occur with sharp turns.

The design of elbows facilitates a gradual change in direction, maintaining system efficiency and preventing potential damage to the pipes or fittings due to abrupt changes in the flow path. When used correctly, elbows help in routing pipes around obstacles or in tight spaces, making them an essential component in pipefitting.

Tees are used to connect three pipes and create a branch but are not suitable for bending pipes at angles. Reducers serve to transition between different pipe sizes and do not alter direction. Caps are used to close the end of a pipe and do not involve any angles or connections in the way elbows do. Thus, elbows are specifically tailored to handle angled connections in piping systems effectively.
