11 Strainers
Strainers are installed in pipe lines ahead of pumps, meters, valves, etc., to protect such equipment against
intrusion of pipe scale, welding spatter and other foreign material.
The use of the proper size strainer together with a basket of suitable mesh pays dividends in reduced
maintenance on mechanisms which are in contact with flowing liquids. When it is known that comparatively
large amounts of lint or iron oxide are present in a stream, a large strainer should be used as these materials
clog up basket screens rapidly-especially if resins, gums or varnishes are also present.
Larger size foreign matter such as pebbles, welding beads, etc., should be removed at frequent intervals to
prevent their abrasive action from damaging the basket screen.
There is a Brodie Strainer of the proper size and pressure rating to accommodate the full line of Brodie Flow
Meters.
