Our Sour Service grades demonstrate improved resistance to Sulfied Stress Corrosion Cracking through their steel microstructure and tight mechanical properties.

GRADES TO RESIST SOUR ENVIRONMENTS
Tenaris has developed sour service grades for oil and gas operations in sour environments. The grades in our SS Series exhibit improved resistance to Sulphide Stress Corrosion (SSC).

An unfavorable combination of H2S dissolved in water, low pH, susceptible structure and high loads, will cause cracks to occur in the steel pipe, which will propagate until failure occurs. Our SS grades are designed to prevent Sulfide Stress Corrosion Cracking (SSC) failures.

The improved resistance to SSC is obtained by the specific design of the steel microstructure and tight control of the mechanical properties.

Our Sour Service steel grades are available in minimum yield strengths ranging from 80Ksi to 125Ksi.
