Notes:
-
GGG 50 Ductile Iron provides excellent strength and toughness for moderate pressure and temperature applications.
-
Screen rating should be selected based on particle size in the medium; confirm with process engineer.
-
Regular screen cleaning and blow-down are required to prevent excessive differential pressure damage.
-
Dimensions must be confirmed based on specific size and pressure rating requirements.
