CRA pipe is applicated in deep well environment containing CO2
Grades: 9%, 13%, 28% Chromium grades and Corrosion resistant alloys(CRA), L80-13Cr, C95-13Cr, P110-13Cr.
13Cr CRA features: Least expensive CRA, most cost effective than using carbon/low alloy steel with inhibition, attractive for tubing applications in offshore production operations, susceptible to corrosion at high temp, to sulfidestress cracking and to crevice corrosion.
