Duplex steel cladded reactor vessels

Introduction

Duplex steel reactor is used especially for chloride-containing process fluids and for ammonium carbamate solutions. In a strongly alkaline chloride- bearing solution, duplex SS gives excellent performance whilst a high-nickel alloy fails after three year because of chloride. Given their excellent corrosion resistance, higher strength and lower cost duplex stainless steels are an attractive alternative to austenitic stainless steel. In oxygen-free carbamate solutions, duplex has proved to be even more corrosion resistant than much more costly materials such as titanium and high-nickel alloys; Application: Chloride-containing solutions;  Ammonium carbamate solutions; Nitric acid and acidic ammonium nirate solutions.
