"Pipeline companies install VALVES along a gas pipeline system
to provide a
means of controlling flow.
The valves may be spaced as
close together as
EVERY FIVE MILES or as far apart as TWENTY MILES
according to
standards established by applicable safety codes.
The valves normally are
open, but when a section of pipeline requires maintenance, operational
engineers close the valves to isolate that section of the pipeline.
Once
isolated, the maintenance crew can vent the gas from that section of the
pipeline and proceed with its work.
