DEFINITIONS
Anchor Line
– Anchor lines are similar to main lines; however,
instead of being continuously installed along the flow line like main
lines, anchor lines are attached to a single point on the flow line,
such as an anchor crossover, and run to a properly rated object
away from the flow line. (Refer to

should ever be used to make up anchor lines. Reference the
previous product rating color code chart for more information.
