to bulk fuel storage tanks by interterminal pipelines which
may be dedicated to serving the particular facility or may be
commercial pipelines handling a number of types or grades of
fuel for more than one user. In some cases, the pipeline will
be an installation pipeline. If different fuel types are
used, separate each type within the receiving facility.
Exercise extreme care to avoid designing a system that could
create damaging surges in the pipeline created by quick
a) Provide pressure-regulating valves to reduce
pipeline pressures to the design pressure of the facility's
piping and equipment. Provide a block valve at both the
upstream and downstream side of each pressure-regulating
valve. Prior to designing any features into the system which
might affect the flow from a pipeline, contact the operator of
the pipeline to ascertain the current operating conditions,
evaluate the use of regulating valves, conduct a surge
analysis of the pipeline, and determine whether the use of
regulating valves is appropriate.
b) Provide a meter at the receiving end of the line
to measure quantities of fuel received. Turbine-type meters
are commonly used for pipeline receipt. However, positive
required flow rate. Consider also the use of alternative
meter technologies such as ultrasonic meters. Compensate for
fuel temperature at the point of custody transfer. Provide a
strainer on the upstream side of the meter and connections for
proving the meter with a portable prover. A meter prover
connection consists of a valve in the main pipeline with a tee
on both the upstream and downstream sides of the valve. The
branch of each of the tees has a valve and a hose connection.
The master meter can be attached to the hose connections.
c) Provide a means for sampling each pipeline
product at a breakout manifold.
d) Provide provisions for a contractor to bolt pig
launchers and receivers to the system for pigging. Arrange
pig receiving connections to avoid introducing pipeline sludge
and sediment into the tanks. Pig launching and receiving
