Saddle bends
1. The rst bend is made at, for example, 45°.
2. Turn the pipe through a half turn and make a
90° bend.
3. Turn the pipe through a half turn again and
make a 45° bend. When the nal 45° bend is
made, the centre line of the pipe must align with
the outside diameter of the segment.
NOTE! The largest saddle bend is obtained if the
rst bend is made at 45°. The size of the saddle
bend is reduced if the angle of the rst bend is
reduced.
Bends one and three must have the same angle.
The angle of bend two must always be twice as
large as the angle of bends one and three.

Figure 4 shows a saddle bend of 45°.
S bends
The rst 90° bend is made as in gure 1 or gure
2. The centre position of the second 90° bend is
based on its distance from the rst 90° bend.
S bends that are close together
Firstly, a 45° bend is made. Turn the pipe through
a half turn, as in gure 3, and make a 45° bend.
The dimension between the bend centres X is ob-
tained on the basis of the segment’s outside dia-
meter and by moving the pipe back and forth in
the tool. NOTE! The dimension X decreases if the
bend is less than 45°.
