Corrosion resistant alloys for demanding applications

Sandvik Materials Technology, Turkey. In highly corrosive conditions, as found in ethylene and fertiliser plants, Sandvik composite tubes provide high resistance to pitting and crevice corrosion. Materials such as Sandvik 3R60 Urea Grade, with low ferrite content for greater resistance to general, inter-granular and pitting and crevice corrosion, can assist in achieving higher output and reduced maintenance. A new premium composite tube, Sanicro™ 67/4L7, offers even greater resistance to stress corrosion cracking and general corrosion for black liquor recovery and other boiler applications in the pulp and paper industry. sandvik Materials Technology – UK sales.smtuk@sandvik.com www.smt.sandvik.com

uptime. Sandvik SAF 2707 HD™ is suitable for aggressive acidic, chloride- containing environments and particularly chlorinated seawater. Tubular solutions supplied by the company include seamless tube and pipe developed for process plants, chemical, petrochemical, refineries, fertiliser plants, pulp and paper mills and power generation plants for reactors, coolers, condensers, boilers and heat exchangers, and hydraulic and instrumentation tubing. “Not only do we have the ability to supply tube and pipe both in seamless and welded options, but a complete piping system solution including, flanges, butt welded fitting, screwed and socket welded fittings and welding supplies all available from stock and competitively priced with short lead times,” commented Mana Yilmaz of

Seamless tube and pipe solutions in corrosion resistant alloys from Sandvik are designed to provide operational benefits in demanding production environments. Process plants, such as chemical, petrochemical, refineries, steel and pulp and paper, rely on the correct selection of seamless tube and pipe for use in coolers, condensers, boilers and heat exchangers, as well as in hydraulic and instrumentation tubing. Sandvik states that its Duplex and Super-Duplex stainless steel tubes, such as Sandvik SAF 2507™, are used extensively in process plants worldwide. Investment in research and develop- ment has led to the introduction of a hyper-duplex grade with greater operational and corrosion capabilities, designed to increase plant operational
