the highest pressure experienced since last reset. Provide
for non-contact resetting of the tell-tale by means of a small
magnet.
e) Provide a pressure gauge on each branch line at
each fueling station on each pier-mounted pipeline. Ensure
that the pressure gauge is legible from the fuel hose
connection array and from the pantograph loading arm location
(if provided).
f) Provide a pressure gauge on each marine loading
arm assembly (if provided). Ensure that the gauge is visible
by the operator.
5.8.9
Stripper Pumps. Provide positive displacement
stripper pumps for emptying loading arms, hoses, and
manifolds. Provide a stripper pump to reclaim each clean
product from each main product line, or connect the product
lines to the oil waste drain line. Conduct an economic
analysis of the two alternatives to determine the appropriate
choice. Larger, longer, or more frequently drained lines will
favor the stripper pump choice. Use a stripper pump on
multiple product lines, but do not exceed acceptable limits of
cross contamination. Provide a dedicated stripper pump to
each sensitive product line, such as aviation turbine fuels.
5.8.10
Excess Flow Sensors. In piping used for both
loading and off-loading, provide a sensor to detect excess
flow that might occur in the event of a line break. This is
accomplished with a diaphragm valve with an excess flow
feature. Design the excess flow sensor to close a remote-
operated block valve.
5.8.11
Solid Cyclonic Separators. In facilities which
receive product by tankers or barge, consider the use of solid
separators in the receiving lines to remove gross impurities
from the incoming product. In systems equipped with
filter/separators in the receiving lines, locate strainers or
cyclonic separators upstream of the filter/separator. Ensure
that there is no slug valve feature on the filter/separator.
Consider the use of automatic water drains.
