What is the difference between an elbow and a bend in piping?

In the realm of piping, there is often confusion between an elbow and a bend. While both are used to change the direction of the piping, there are key differences between the two.

Elbow

An elbow is a specific type of piping fitting that allows for a smooth change in direction. Elbows are typically pre-fabricated and come in standard angles such as 45 degrees or 90 degrees. They are often used when a precise angle is needed in the piping system.

Bend

On the other hand, a bend is a generic term for any section of piping that has been curved or bent to change direction. Bends are usually custom-made on-site and can be formed to any angle required. While elbows provide a more precise angle, bends offer flexibility in creating custom angles.

So, in summary, the main difference between an elbow and a bend in piping is that elbows are pre-fabricated fittings with specific angles, while bends are custom-made sections of piping that can be curved to any desired angle.

Understanding the difference between elbows and bends is crucial for proper installation and maintenance of piping systems.
