Application

The 90° pipe elbows is used to connect tubes at a 90° angle. As the name suggests, the elbow is always a right-angle in shape. Such type of elbow is also known as "90 bends or 90 ells". This is a pipe fitting device which is bent in such a way to produce 90° change in the direction of flow of the fluid/gas in the pipe. The elbow is used to change the direction in piping and is also sometimes called a "quarter bend".

A 90° elbow attaches readily to pipes of various materials like plastic, copper, cast iron, steel, lead, rubber etc. In other words, the 90° elbows are used to provide a joint between two pipes at right angles to each other. They are used as railing ends or corners on a level installation.

Materials used:
Materials used in 90° angle are as follows:

• PVC
• Rubber
• Copper
• Cast iron
• Brass
• Stainless steel
• Bronze
• Galvanized steel
• Aluminum etc.

Types of 90° elbows:
90° elbows are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows:

SR (Short Radius) Elbows: These elbows have a Center-to-Face dimension of 1.0 X diameter. They are typically used in tight areas where clearance is the main issue.

LR (Long Radius) Elbows: These elbows have a Center-to-Face dimension of 1.5 X diameter. They are the most common type of elbow and used when space is available and flow is more critical.

Size and Dimension:
90° elbows are available in various sizes. To get the actual size, just take the measurements of A and B as shown in the figure.


Application of 90° elbows:
The main application area of a 90° elbow is to connect hoses to valves, water pressure pumps, and deck drains. 90° elbows help to make dust hose take that quick turn at the corner. These elbows can be used on instrumentation, process and control systems and equipment employed in chemical, petroleum, fluid power, electronic and pulp and paper plants.
