Super-duplex tubing
Published: 05 November, 2015
When an international oil and gas company built a challenging offshore gas production platform in Southeast Asia the new design called for an increase in the working pressure of the platform's hydraulic tubes from 8,000 psi to up to 12,000 psi. Unfortunately, standard tubing of austenitic grade UNS S08904 – known as 904L – was reportedly incapable of handling pressures above 8,000 psi.
To accommodate this increase in pressure Sandvik says it recommended and supplied super--duplex Sandvik SAF 2507 tube, in order to increase productivity by withstanding pressures of up to 12,000 psi – a 50% improvement over the standard 904L. In addition, because it is a lighter material, the super-¬duplex tube was said to be easier to install.
