Glossary of Bending Terms with Illustrations
1.
amount of offset
— the dis-
tance that the conduit or pipe
must be re-routed to avoid an
obstruction; see
offset
in this
glossary and “Offset” bending
instructions 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 suc-
cessive bends that make
up an offset or a three-bend
saddle
4.
depth of offse
t — same as
amount of offset
5.
height of offset
— same as
amount of offset
6.
leg length
— the distance from
the end of a horizontal section
of conduit or pipe to the bend;
measured from the end to the
center line, inside edge, or
outside edge of the conduit
or pipe
7.
90° bend
— any bend that
changes the direction of the
conduit or pipe by 90 degrees
8.
O.D.
— the size of any piece of
conduit or pipe as measured by
its outside diameter
9.
offset bend
— two bends with
the same degree of bend; used
to avoid an obstruction block-
ing the run of the conduit or
pipe
10.
ram travel
— the distance that
the ram of hydraulic bender
moves to accomplish a particu-
lar bend; inches of ram travel
are proportionate to degrees of
bend
11.
rise
— the distance from the
end of a vertical section of
conduit or pipe to the bend;
measured from the end to the
center line, inside edge, or
outside edge of the conduit or
pipe
12.
shrink
— the amount of conduit
“lost” when laying out an
offset bend working toward an
obstruction; see the detailed
explanation under “Offset”
bending in this manual
13.
springback
— the amount,
measured in degrees, that
a conduit or pipe tends to
straighten after being bent
14.
stub
— same as
rise
15.
stub-up
— same as
rise
