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 Securing SPM
®
FSR System
Ends later in this document) Only appropriately rated Spines
should ever be used to make up anchor lines. Reference the
previous product rating color code chart for more information.
