on suction and discharge lines for interterminal pipeline
pumping stations and on the incoming line at the delivery
terminal of each such pipeline.
Strainers. Require a strainer to protect
positive suction head of the pump. Whether or not strainers
require a spool piece so that temporary strainers can be
installed during startup of the system. Strainers are
required on the suction side of all positive displacement
pumps and meters. Strainers are not required upstream of
filter/separators or hydraulically operated diaphragm control
valves, except upstream of filter/separators which are
upstream of operating storage tanks. Also:
a) Use flanged strainers constructed of steel and
fitted with removable baskets of fine Monel metal or stainless
steel mesh with large mesh reinforcements.
