Centerway - Stainless Steel Elbow
The elbow radius mean curvature radius. If the radius is the same as pipe diameter, it called short radius elbow, also called 5R elbow, normally for low pressure and low speed pipelines. If the radius is larger than pipe diameter. Ral.5 Diameter, then we call it a long radius elbow (LR Elbow), applied for high pressure and high flow rate pipelines.

According to fluid (low direction of the pipes, elbows can be divided into different degrees, such as 45 degree. 90 degree. 180 degree, which ore most common elbows. Also theie are 60 degree and 120 degree elbows for some special pipelines. This degree is just an representation of the angle by which the fluid flow is going to change after flowing through the said elbow.
Types of Elbows based on Connection with Pipe
Butt Welded Elbow
Butt weld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt welded elbows have beveled ends to allow for ease of welding. This bevel allows for full penetration weld in most of the cases. Butt welded elbows are mainly used for elbow with higher pressure and temperature.
Socket Welded Elbow
Socket weld elbow is also welded to the pipe and fittings end. Unlike the butt weld elbow, the socket weld elbow has a trapezoidal area at the end. We can insert pipe end into this area {the diameter of SW elbow is matched with the outer diameter of pipe), then do welding work to connect them together. Therefore, the actual diameter of SW elbow end is greater than the elbow diameter.
Threaded Elbow
The shape of threaded elbow is similar to the SW elbow, except that the inner surface of the trapezoidal area has been machined into thread. It is easier to install and remove, good for pipeline repair and maintenance.
