Sandvik 2RE69

通用系列： Steel - Wrought - Stainless - Austenitic • 提供方： Sandvik Materials Technology

Sandvik 2RE69 is a fully austenitic stainless steel with extra low carbon and impurity contents. The grade is characterized by:

Excellent resistance to corrosion in ammonium carbamate and nitric acid

Excellent resistance to intergranular corrosion

High resistance to pitting and crevice corrosion

Good weldability

Sandvik 2RE69 has been developed primarily to cope with the severe corrosive conditions existing in the urea industry. The longest service life is so far 35 years, which confirms the optimal properties for the grade Sandvik 2RE69 in urea strippers.

Applications
Sandvik 2RE69 is used successfully in all critical high-pressure units of modern urea processes, such as:

Stripper tubes: Stamicarbon, Montedison IDR

Outerlayer of bimetallic ( stripper tubes): Saipem

Ferrules: All processes

Carbamate condensers: All processes

Decomposers: Montedison

Reactor coils: UTI

Sandvik 2RE69 has also found extensive use in other corrosive environments in fertilizer plants, such as:

Nitric acid cooler/condensers cooled with polluted cooling water

Heating coils and pipe in NPK plants - Norsk Hydro process
