Accurately Bending Pipes: What Info Do You Need?

[rayzerclip]

Hi everyone,
Im a draftsman that has to give a drawing for pipe bending, what information is needed so the pipe can be bent accurately?

Thanks

Assuming the pipe itself has been properly specified, you will need the radius of curvature of the bend and the angle of the bend.

If accuracy matters you had better specify a tolerance for the radius and angle.
