FITTINGS
If standard symbols for fittings like tees, elbows,
crossings, and so forth are not shown on a drawing,
they are represented by a continuous line. The circular
symbol for a tee or elbow may be used when it is
necessary to show the piping coming toward or
moving away from the viewer. Figure 5-8, views A
and B, show circular symbols for a connection with
and without flanges.
Symbols and Markings
MIL-STD-17B, part I, lists mechanical symbols
used on piping prints other than those for
aeronautical, aerospacecraft, and spacecraft, which
are listed in MIL-STD-17B, part II. Figure 5-9 shows
common symbols from MIL-STD-17B, part I. Note
that the symbols may show types of connections
