Global technology engineering group Sandvik will present corrosion resistant alloys, including its new Sandvik SAF 3207 (UNS S33207) hyper-duplex stainless steel at NACE CORROSION 2015, the company announced today.
NACE CORROSION 2015, the world's largest corrosion conference and exhibition, will take place in Dallas, Texas, between March 15-19, at the Kay Bailey Hutchinson Convention Center. Sandvik will exhibit its full range of advanced corrosion resistant alloys, including duplex and super-duplex grades, as well as the new Sandvik SAF 3207, which was developed to combine high strength in the solution annealed condition, with localized corrosion resistance properties that are superior to super-duplex grades.
Sandvik SAF 3207 can be utilized for OCTG tubing, raw seawater injection, umbilicals and other applications where high strength and thinner walls are required. It also provides improved resistance to chloride induced corrosion and cracking in high temperature, high chloride environments, the company said.
“We are very excited to showcase our high performance, corrosion resistant alloys to the anticipated turnout of more than 7,000 corrosion professionals at CORROSION 2015," said Magnus Olaison, Sandvik Materials Technology's Senior Development Engineer, Oil & Gas Tube. "It’s an invaluable opportunity to explain how hyper-duplex grades like Sandvik SAF 3207 are helping customers to achieve safer operations in downhole applications, as well as a high corrosion resistance in aerated seawater environments, for greatly reduced costs, maintenance and downtime."
Testing in accordance with NACE TM0177 found that Sandvik SAF 3207 performs at higher H2S partial pressures than the present limit in the NACE MR0175 standard for super duplex. With a Pitting Resistant Equivalent Number (PREN) of 50, compared to the current limit for duplex material which is PREN 40 to 45, the hyper-duplex grade exhibited no cracks or signs of corrosion at pressures of up to 5 psi H2S.
