Symbols and
markings
MIL-STD-17B, part I, lists mechanical symbols used on piping prints other
than those used for aeronautical, aerospacecraft, and spacecraft (listed in part
II).
When an item is not covered in the standards, the responsible or
originating activity designs a suitable symbol and explains it in a note. When
more than one piping system of the same kind appears on a print, use letters
added to the symbols to differentiate between the systems.
Figure 4-50 is a list of common pipe line symbols.
