320 million feet. Zero Failures
Hyper-duplex leads the way. Our popular Sandvik SAF 2507® super duplex is very good. But our new hyper-duplex stainless steel, Sandvik SAF 3207 HD™ is even better when it comes to yield strength, corrosion resistance and fatigue properties.
Hyper-duplex vs super-duplex
Here you see how our hyper-duplex achieves a 25% increase in yield strength, compared to super duplex. As a result, you can coil tubes into smaller reels with longer umbilical lengths, making more efficient use of the installation vessels. Thinner walls and lighter installations help you reach and operate ultra-deep wells that were previously too costly or too complex to exploit.
