Industrial Trial Production and Performance Evaluation of BT80S-5Cr Anti-CO₂/H₂S Corrosion Tubing

The BT80S-5Cr anti-CO₂/H₂S corrosion tubing is trial produced with the 10Cr5MoVRE steel. Described here in the essay is the industrial trial production process of the said tubing.Also analyzed are the metallographic structure, the mechanical properties, the corrosion resistance as well as the full size physical evaluation result of the said tubing. It is concluded via the analysis that the metallurgical quality, the metallographic structure, and the mechanical properties, SSC resistance of the tubing all conform to applicable technical requirements;the tubing’s uniform corrosion rate is 30%~50% lower than the 3Cr steel of the same grade;its tensile failure load is 55% higher than the value as specified under applicable technical requirement, and its internal pressure to failure load is also 70% higher than relevant technical requirement.
