You can virtually a 3D pipe bend by using a bend machine. This is can create a lot of different single and multiple bends making the pieces form into shapes.
A 3D bend is a pipe bend that the bend radius is 3 times the pipe outside diameter.
wrought pipe bends means straight pipe bend using rotary draw pipe bender. or pipe bend by any method
Worught Pipe Bend
There is no difference. Different suppliers and contractor describe the same situation with 3R or 3D. Here is how to think about it. A piping segment is formed or bent at a radius. The radius is measured at the centerline of the bend. The radius of the bend centerline is 3 times the nominal diameter of the piping segment being bent. 3R means the bend radii is three times the nominal pipe diameter. 3D means three times the nominal pipe diameter is the bend radii of the piping segment. Caution don't begin to convert 3R to 1.5D. Not applicable with this terminology. Standard long ells can be purchased with 3R bends, being 10 inch pipe ells have a bend radii of 30 inches.

The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10" diameter pipe, the radius of the centerline of the bend would be 50 inches.
Where it is not possible to bend a pipe due to lack of equipments or the thickness of the pipe, the miter bend is made by cutting the pipes at desired angles.
Bend meter is a type of pipe which are bend may be sharply or 90 degree . In fluid mechanics we calculate the losses inside the pipe .in which losses are more.
pipe bending is a method to enhance the fabrication capabilities of pipe work and plumbing fixtures
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
The pipe has been bent in a former, no corner piece is then required.
