Pipe Bending Radius: 3D Bend, 5D Bend, 6D, 8D and customized
Bending Degrees: 15°, 22.5°, 30°, 45°, 60°, 90°, 180° and customized

3D Bend

3D bend radius in 3D,  means the bend radius is 3 times of pipe outside diameter. For example if a 3D bend used in a 10 inch pipelines, 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 smooth performance to change pipeline direction than 3D bend.

Large Diameter Pipe Bend / Bending

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