OBLIQUE JOINTS.—When the joints between
view is required to find the true length of the chords
the pipe and transition piece are not perpendicular to
between the end points of the elements. The
the pipe axis (fig. 8-21), then a transition piece should
development is then constructed in the same way as the
be developed. Since the top and bottom of the
development used to connect two circular pipes with
transition piece will be elliptical, a partial auxiliary
parallel joints.
