Sandvik products to star at Nitrogen + Syngas 2014

Sandvik’s extensive expertise and product portfolio will feature at Nitrogen + Syngas 2014 with special high-alloy, seamless stainless steel tubing and materials developed for aggressive applications in fertilizer processing plant. Products featured will include Sandvik 3R60 Urea Grade, Sandvik 2RE69 and Safurex stainless steels specially designed for service in highly corrosive conditions in the urea industry.
Widely used in high-pressure piping, Sandvik 3R60 Urea Grade is a high-purity variant of ASTM 316L with a low ferrite content, which makes it highly resistant to general and intergranular corrosion. Sandvik 2RE69 provides excellent resistance to corrosion in ammonium carbamate and nitric acid with excellent resistance to intergranular corrosion as well as high resistance to pitting and crevice corrosion. Originally developed for stripper tubes used in the production of urea, it is also highly resistant to inorganic acids. High chromium content of 25% provides greater resistance to oxidation, improved hardenability and strength, while a high nickel content offers greater corrosion and heat resistance.

The high alloy duplex stainless steel Safurex, developed together with Stamicarbon, is widely used in stripper tubes, pool condenser tubes, ferrules, high-pressure piping, scrubbers, linings, overlay welding, reactor trays and for high-pressure valves.
