Materials for Saline Water Desalination and Oilfield Brine Pumps (11004)
Nickel Development Institute reference book series, 2nd ed., 1994. Materials for saline water pumps include cast irons, austenitic cast irons, copper alloys, nickel-base alloys and stainless steels. In selecting corrosion-resisting materials for the several components of saline water pumps there are four principal considerations: corrosion resistance in clean seawater, and in modified saline waters that pumps commonly encounter; resistance to high velocity and turbulence; resistance to stagnant saline water encountered during standby periods; and galvanic compatibility: the pump case should galvanically protect the internals. These considerations are addressed, as is experience with available alloys.
