Material Selection for Phosphorous Acid Injection
Material Selection for Phosphorous Acid Injection
(OP)
Would super-duplex stainless steel be a suitable long-term material for tubing in a system injecting a mixture of about 70% phosphorous acid, water, 0.02% hydrochloric acid, and up to 4% methanol-based corrosion inhibitor at Gulf of Mexico ambient temperatures? Must also consider certain amount of chlorides (maybe up to 300 ppm).
Suggestions and further questions certainly welcome.
