Erosive Agent

[chtimi]

I would like to know if for a produced water injection: pumping temperature: 120°F to 160 max
TDS: 3500mg - 25000 mg
Chloride concentration : >100ppm
Viscosity: 1.3
Density : 1.004 à 1.01

The choice with a cast casing in A 216WCB with internals ( impeller, shaft, rings..)in 13%Cr is correct, or if its better to choose a cast casing in 13% Cr with internals in 13%Cr?

Thank you for your help

The benefit of the carbon steel casing is that if offers some amount of cathodic protection to the other parts.
