Pipe Elbow

pipe elbow is a fitting that is used to change the direction of a pipe's flow by redirecting it at an angle. Pipe elbows are commonly used in plumbing, heating, and ventilation systems, as well as in industrial and commercial applications.What is Elbow Radius?

The elbow radius mean curvature radius. f the radius is the same as pipe diameter it called short radius elbow, also called SR elbow.normally for low pressure and low speed pipelines.

Pipe elbows are available in a variety of angles, typically ranging from 22.5 degrees to 90 degrees, with 45 degrees being the most common. Elbows can be manufactured with different radii of curvature, which determine the smoothness of the bend.

lf the radius is larger than pipe diameter,R≥1.5 Diameter, then we cal it a long radius elbow(LR Elbow), applied for high pressure andhigh flow rate pipelines.

Classified by Direction Angle

As we know,.according to fuid direction of the pipelines,elbow can be divided into different degrees, such as 45 degree, 9o degree,180degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.
