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 in 90° angle are as follows:
Types of 90° elbows:
- Cast iron
- Stainless steel
- Galvanized steel
- Aluminum etc.
90° elbows are manufactured as SR (Short Radius) elbows and LR
(Long Radius) elbows:
Size and Dimension:
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
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:
What should buyers look for bulk purchase of 90°
The buyers should always consider for maximum assurance of reliable
performance, such as high pressure, impulse, vibration, vacuum and
temperature. Some specifications to look for are:
- Light weight, convenient to transport and handle
- High strength
- Less resistance
- Corrosion resistance
- No pipe furring
- Sound insulation
- Easy to install
- Long lifespan
- Low cost
- Recyclable (optional)
- For water pipes, healthy and non-toxic, bacterial neutral,
conforming to drinking water standards
- Resistant to high temperatures (110°C)
- Reliable installation
- Good heat preservation
- Excellent design which ensures suitability for both exposed
and hidden installation etc.
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
