12D Pipe bending

A 12D is a pipe bend that the bend radius is 3 times the pipe outside diameter.

What is 12D in bend pipe?

The RADIUS of a 12D 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.
How do you know a 3d or 12d bend?

It is the radius of bend of the elbow with reference to a point,the point is determined by the intersection of two lines from the elbows socket end (which makes the shape of one quater of a circle). The bend ie; 3d,5d,7d,12d is determined from that point of intersection as a multiple of elbows diameter.
Pipe bend, Bend pipe, Pipe bending, ANSI, ISO, JIS and DIN Standards, Measures 1/2 to 56 Inches.

The bend is used to change the direction of run of pipe.it advantage is can matach long distance transition requirements,so it is commonly that bends dimension according to customer design. usually,the bends consist of 3D,5D,7D even 12D series.carbon steel bend
