Illustrated Bending Glossary

10. leg length—the distance
Greenlee / A Textron Company
1. amount of offset—the
distance that the conduit or
pipe must be re-routed to
avoid an obstruction; refer
to offset bend in this glos-
sary and "Laying Out Offset
Bends" in this manual
2. 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
3. center-to-center
distance—the distance
between the succes-
sive bends that make up
an offset or a three-bend
saddle
4. degrees per shot—a
segment bending term
which refers to the amount
of bend accomplished each
time the conduit is bent;
to achieve a smooth bend,
each shot must accom-
plish the same number of
degrees of bend
5. depth of offset—same as
amount of offset
6. developed length—the
actual length of pipe
that will be bent; refer to
distance "d" in the following
illustration
7. gain—the difference
between the straight-line
distance (a + a) and the
shorter radial distance, (d)
where:
θ = angle of bend
r = the centerline bending
radius of the
bending shoe
8. height of offset—same as
amount of offset
9. kick—single bend of less
than 90°
from the end of a horizontal
section of conduit or pipe
to the bend; measured from
the end to the outside edge
of the conduit or pipe
884 and 885 Hydraulic Benders
11. 90° bend—any bend that
12. number of bending shots—a
13. O.D.—the size of any piece of
14. offset bend—two bends with
15. ram travel—the distance
16. rise—the distance from the
17. segment bend—any bend
18. shot—a single bend; a shot
19. shrink—the amount of conduit
20. springback—the amount,
21. stub—same as rise
22. stub-up—same as rise

changes the direction of the
conduit or pipe by 90°
segment bending term which
refers to the total number of
small bends that are required
to make up a more gradual
segment bend
conduit or pipe as measured
by its outside diameter
the same degree of bend;
used to avoid an obstruction
blocking the run of the conduit
or pipe
that the ram of hydraulic
bender moves to accomplish
a particular bend; inches of
ram travel are proportionate to
degrees of bend
end of a vertical section of
conduit or pipe to the bend;
measured to the centerline of
the conduit or pipe
formed by a series of bends of
a few degrees each, rather
than a single bend; allows a
more gradual bend
may accomplish a complete
bend or, when making a
segment bend, several shots
may be required to make a
more gradual bend
"lost" when laying out an
offset bend working toward
an obstruction; refer to the
explanation under "Laying Out
Offset Bends" in this manual
measured in degrees, that
a conduit or pipe tends to
straighten after being bent
