Final Note:
We have discussed the major ancillary or accessory equip-
ment used in many piping systems. It is important to point out that
other accessories are commonly used in piping systems (e.g., rotary
pressure joints, actuators, intensifiers, pneumatic pressure line acces-
sories); however, discussion of these accessories is beyond the scope of
this text.
