All You Need To Know About 90 Deg Elbow

90 Deg Elbow

An elbow is a pipe fitting installed between two straight pipe sections in plumbing. The elbow can be used to change the flow direction or connect pipes of different sizes or materials. One of the most commonly used elbow fittings is the 90-degree elbow. As the name suggests, this type of elbow has a 90-degree angle between its two connecting ends. This blog post will explore the features, applications, and types of 90 deg elbow.

What is 90 Deg Elbow?

A 90 Deg Elbow is a pipe fitting used to connect two lengths of tubing or pipe at an angle of 90 degrees. These elbows are typically made from copper, stainless steel, carbon steel or PVC. They are most commonly used in plumbing and HVAC systems to change the direction of the flow of water within a pipeline. A 90 90-degree elbow is essential for any piping work since it not only helps avoid system leaks but also reduces pressure and ensures smooth flow throughout the system. Installing this elbow properly can help increase increase the life span of your plumbing system and provide efficient outcomes!

Features of 90 Deg Elbow

A 90 degree elbow can be made from different materials such as brass, copper, PVC, stainless steel, or iron. It is designed to have equal or unequal bore sizes on its two ends, depending on the requirements of the piping system. The ends of a 90-degree elbow can be threaded, soldered, or welded to the pipes. They can also have female or male ends for a versatile connection. 90-degree elbows are available in sizes ranging from small 1/8″ elbows to large 48″ elbows.

Applications of 90 Deg Elbow

The prime use of a 90 degree elbow is to change the flow direction in a piping system. This is essential when bending a pipe would cause potential damage or a reduction in flow. For example, if a pipe needs to pass through a wall and continue along another wall, a 90-degree elbow is used to make the transition. 90-degree elbows are also used for connecting a pipe to a fitting or equipment at right angles to the pipeline. Another common use of a 90-degree elbow is to reduce friction losses in the system.

Types of 90 Deg Elbow

There are two main types of 90-degree elbows – long radius (LR) and short radius (SR) elbows. Long-radius elbows have a longer centerline radius than the pipe diameter, making them less abrupt in the change of direction. They are mainly used in low-pressure and low-velocity systems. Short-radius elbows have a radius equal to the pipe diameter, making them more abrupt in the change of direction. They are used for high-pressure and high-velocity systems. Choosing the right type of 90-degree elbow depends on the application requirements.

Installation of 90 Deg Elbow

Installing a 90-degree elbow is a simple process that requires some basic plumbing tools. The first step is to ensure the pipe ends are clean and free from rust, debris or burrs. Next, the elbow may need to be threaded, soldered or welded to the pipes, depending on the type of connection. It’s important to align the centerline of the elbow with that of the pipes to avoid any obstructions or kinks in the system. Lastly, the elbow joints should be tested for leaks before operating the system.

Conclusion:

In summary, a 90-degree elbow is a critical plumbing fitting used in various applications. It is available in different materials, bore sizes, and types, each suited to different system requirements. Choosing the right type of elbow can improve system efficiency, reduce friction losses, and prolong the life of the piping system. Always ensure proper installation and testing procedures are followed to prevent leaks and ensure proper functionality.
