An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 180° or 90° angle, though 45° elbows are also made. The ends may be machined for butt welding (SW) or socketed welding(SW) etc.

Most elbows are available in short radius or long radius variants. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.

Elbows are categorized based on various design features as below:

Long Radius (LR) Elbow is also called LR elbow – means the radius is 1.5 times the pipe diameter
- L/R 45°Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
- L/R 90°Elbow: Long radius 90 degree elbow changes the direction by 90 degrees.
- L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.
Short Radius (SR) Elbow is also called SR elbow, – means the radius is 1.0 times the pipe diameter
- Short radiu 45°Elbow: Short radius 45° elbow changes the direction by 45 degrees.
- Short radius 90°Elbow: Short Radius 90° elbow is same as LR90 except for the measurement between end of elbow to center line is 1 x NPS.
- Short radius 180° Elbow: Short Radius 180° return bend allows complete reversal of flow

Size range:

Seamless elbow: 1/2"-24" DN15-DN600
Welding elbow: 6"-72" DN150-DN1800

Abrasion resistant elobw

SHS-self-propagating ceramic composite steel pipe and fittings, the new generation of wearable and corrosion resistant engineering pipeline, belongs to "863" Hi-tech Plan products.

Ceramic Lined Elbows could be also applied in the parts of concrete pump owing to their advantages especially the low weight which helps to avoid the jam during the transport of concrete.
Ceramic Tile lined elbows
Backpack wear-resistant ceramic lined elbow
Rare Earth Wear Resistant alloy Elbow

It is the ideal wearable and corrosion resistant engineering pipeline, with wear resistance 15 times higher than common steel pipe, smooth inner surface, and favorable liquor resistance.

Butt Weld Pipe Fitting Bevel

All welded pipe fittings have bevelled end to allow for ease of welding.
This bevel allows for full penetration weld in most cases.
There are two types of bevels;
Plain Bevel and Compound Bevel: according to the bevel of welding pipe fittings construction .

Industrial Processes: Bending, squeezing, pressing, forging, machining and more ANSI/ASME B16.25, Buttwelding Ends
ANSI/ASME B16.25 Standard covers the preparation of butt welding ends of piping components to be joined into a piping system by welding.

Application of pipe elbows:

Petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, etc.

ELL & ELLS

A wing of a building at right angles to the main structure.
A right-angled bend in a pipe or conduit; an elbow.
