The longer and stiffer the body of the pig, the longer radius the bend will need to be (Elbow tends to refer to piping not pipelines)

Some can round 1.5D bends, others need 3D or 5D minium.

Different function or assembly of pigs may be used on the different size of bend, for example 1.5D, 3D, or 5D bends of the pipeline. See the pig manufacturer for detail application.
