High-Pressure Tube Splice.
SUMMARY
Three types of metal tubing are used in aircraft plumbing systems:
aluminum alloy, stainless steel, and copper.
Aluminum alloy tubing
is the most widely used because of its workability, resistance to
corrosion, and light weight. Stainless steel tubing is used in high-
pressure systems and in places where the tubing is exposed to
possible flying-object damage or ground-handling mishaps.
Copper
tubing is normally used only in high-pressure oxygen systems.
In routing replacement lines, the path of the original line is
usually followed. However, when a different route must be used, care
must be taken in planning the layout to ensure the bends in the
tubing do not exceed the minimum bend radius specified for the
particular type of tubing. Care must also be taken not to route the
tubing without bends as this allows for no flexibility in response to
vibrations or pressure fluctuations.
