strainer must be removed for cleaning. Because of its large size, it has the ability to store
large quantities of dirt and so has a lower pressure loss than a similar sized Y strainer.
MATERIALS OF CONSTRUCTION
Strainer Bodies
The materials used most commonly for strainer bodies are cast iron, bronze, carbon steel,
stainless steel, and plastic.
Because of its low initial cost, cast iron is the most popular strainer body. It is used in
systems where the pressure and temperature of the water are not high and the system is
not subject to high thermal or mechanical shock. Cast iron is mostly used for larger size
potable water lines and many nonpotable water systems in addition to a variety of other
product and process uses.
