Customer stories
“Pre-Salt has the critical combination for the Pipes: necessity of high Yield Strength due to the well depths and salt loads and H2S presence (corrosion), what leads to the usage of Sour Service metallurgies. The SS pipes are being used for almost all the Pre-Salt wells in Brazil and helping the customers to have a lighter string while keeping the high mechanical resistance.”
