Illustrated Bending Glossary
back-to-back bend
— any U-shaped bend formed by two
parallel 90° bends with a straight section of conduit or pipe
between the bends.
center-to-center distance
— the distance between the
successive bends that make up an offset or a three-bend
saddle.
developed length
— the actual length of pipe that will be
bent; refer to distance “d” in the illustration at left.
gain
— the difference between the straight-line distance
(a + a) and the shorter radial distance, (d) where:
q
= angle of bend
r = the centerline bending radius of the bending shoe
kick
— single bend of less than 90°
leg length
— the distance from the end of a straight section
of conduit or pipe to the bend; measured from the end to the
outside edge of the conduit or pipe.
rise
— the distance from the end of a straight section of
conduit or pipe to the bend; measured from the end to the
center line of the conduit or pipe. Also called stub or
stub-up.

conduit or pipe tends to straighten after being bent.
