Sandvik Steel informs us that it has extended its manufacturing capability for seamless titanium and zirconium tubes with the availability of two additional titanium grades.
The two new grades, designated ASTM/ASME grades 12 and 26 claim enhanced corrosion properties for heat exchanger and piping applications in the hydro metallurgy, LNG, petrochemical refining and salt refining industries. ASTWASME grade 12 is a titanium alloy containing 0.03 per cent molybdenum and 0.8 per cent nickel. ASTM/ASME grade 26 is an unalloyed titanium with the addition of 0.08-0.14 per cent ruthenium to increase corrosion resistance.
Both grade 12 and grade 26 are said to be particularly well suited to use in heat exchangers and coolers – using chlorinated seawater as a coolant when there are risks of crevice corrosion. Grade 12, in addition, claims enhanced heat, erosion and erosion corrosion resistance. Both grades are also stated to be designed to provide enhanced resistance to dilute, reducing acids and crevice corrosion or pitting in hot (m75°C) chloride or halide solutions.
Sandvik Steel's manufacture of seamless titanium and zirconium tubes is undertaken with a completely integrated process that begins with the melting of the titanium or zirconium sponge or from zirconium ingots and ends with the finished seamless tubes. The production process has been specially designed to work with non-ferrous metals.
