Classification of elbow forgings

Elbow forging is a part used to change the flow direction of the pipeline, according to its Angle and radius, elbow forging can be divided into the following categories:

Standard elbow: Standard elbow is made in accordance with a specific Angle of the elbow, the common Angle is 45 degrees, 90 degrees, 180 degrees and so on. The curve radius of a standard elbow is usually 1.5 or 2 times the diameter of the pipe. Standard elbows are suitable for most piping systems.

Long radius elbow: The curve radius of a long radius elbow is usually 1.5 times the diameter of the pipe. Compared to standard elbows, long radius elbows have a smoother flow path and less resistance to fluids, so they are often used at high flow rates or in situations where pressure loss needs to be reduced.

Short radius elbow: The curve radius of the short radius elbow is usually 1 times the diameter of the pipe. Although the short radius elbow is not as smooth as the long radius elbow, its size is more compact and suitable for space limited cases.

Special Angle elbow: In addition to the common 45 degrees, 90 degrees and 180 degrees elbow, there are other special Angle elbow, such as 30 degrees, 60 degrees and so on. These elbows are usually designed to meet specific engineering requirements.

It should be noted that the Angle of the elbow forging refers to the Angle of the pipe flow direction change, and the curve radius refers to the curve radius of the bend inside the bend. The selection of suitable elbow forgings should be determined according to the specific engineering requirements and the parameters of the pipeline system.
