How do you calculate the radius of a 5D bend?

Published in Pipe Bending 1 min read

The radius of a 5D bend is calculated by multiplying the outside diameter of the pipe by 5.

Here's a breakdown:

  • 5D Bend Definition: A "5D bend" refers to a pipe bend where the bending radius is 5 times the pipe's nominal or outside diameter.

  • Calculation:

    Radius of Bend = 5 * (Outside Diameter of Pipe)

  • Example:

    If you have a pipe with an outside diameter of 10 inches:

    Radius of the 5D bend = 5 * 10 inches = 50 inches

Therefore, the radius of the centerline of the 5D bend would be 50 inches in this example.
