Carbon Steel Butt Weld Pipe Bends

Buttweld Steel Pipe Bend 3D 5D 8D

A butt weld steel pipe bend is a pipe that is used to change the pipeline direction. Common use radius bend in 3D bend and 5D bend, it is similar to a pipe elbow, but a different pipe bend is longer than an elbow and is usually manufactured for the specific needs.

So depends on the different bending radius (R) to distinguish bend and an elbow.

In case the bending radius is more than 2 times of D (diameter), it is a pipe bend. Like 3D bend, 5D bend, 6D pipe bend, 8D pipe bend.
In case bending radius in 1D or 1.5D, it is an elbow. (short radius elbow 1D and long radius elbow 1.5D).

Buttweld pipe bend types: 3D, 5D Pipe Bend:

3D and 5D bends are most commonly used in long pipelines, since they provide better efficiency in changing directions.

 3D Pipe Bend:

3D bend radius in 3D means the bend radius is 3 times of pipe outside diameter. For example, if a 3D bend is used in a 10-inch pipeline, the bend radius would be 30 inches.

5D Bend:

5D bend means the bend radius is 5 times of pipe nominal diameter. It provides better smoother performance to change the pipeline direction than a 3D bend.

The radius becomes bigger, the length of the pipe bend becomes bigger. 

Large Diameter Pipe Bend / Bending

Steel pipe bending is usually required in large diameters in oil and gas pipelines, since it has better capacity to transport the material, and long pipelines will need different radii of pipe bends to be installed in complex conditions.
