Sandvik Materials Technology will be displaying a comprehensive range of tubular and bar products at Tube 2010, including its material grade introductions. Under the theme of “Challenge your expectations,” the company will be showing new grades. Introduction of the very latest hyper-duplex stainless steel Sandvik SAF 3207 HD® optimises material strength and corrosion resistance, it extends the properties of Sandvik’s industry standard super-duplex grade, Sandvik SAF 2507. Use of the new grade makes it possible to develop installations and explore new oil and gas fields that were previously thought to be too expensive and technologically unattainable. Developed for use in deeper more remote subsea umbilicals operating in aggressive environments, Sandvik SAF 3207 has a higher yield strength to withstand increased pressures, facilitating thinner wall umbilicals that reduce reel sizes and lower installation costs. It extends the operating capabilities of hyper duplex materials having a high tensile strength of 980 – 1180MPa and increases the operating temperature up to 90C. Another specifically developed hyper-duplex stainless steel is Sandvik SAF 2707 HD® designed for service in highly corrosive conditions, such as seawater cooled heat exchangers. It is particularly suited to aggressive, chloride-containing environments and displays excellent resistance to pitting. This makes it suitable for chemical, petrochemical and refinery industries, to meet higher industry demands on performance whilst maintaining the reliability and safety of equipment.
