Feeding the world by increasing plant reliability and performance
Fouling. Plugging. Cleaning. You’ve seen it all before. Such risks are costly and to be avoided. This often comes down to selecting the right tube material for your application. With highly corrosive conditions, standard stainless steel or traditional duplexes may not be enough.
Innovative solutions
To solve these tough challenges, our R&D team continues to pioneer new corrosion-resistant materials. At the same time, our process experts work directly with customers to identify material selection solutions for today’s most demanding fertilizer production conditions. Clearly, fertilizer is needed to feed the world, and we intend to be there at your side – working to advance your productivity.
Strategic Inventory
Raw material held in inventory for consistent, short lead times.
Nitric acid solutions
Alleima® 2RE10 is our solution developed specifically for nitric acid applications. Its controlled chemical composition limits impurities such as C, Si, P and S, minimizing segregation in the grain boundaries and reducing the risks of intergranular corrosion. Thus, it offers higher corrosion resistance than standard 304L stainless steel.
Phosphoric acid solution
Graphite heat exchangers often represent a maintenance challenge for phosphoric acid producers. The brittle nature of the material can lead to broken tubes and loss of production. Sanicro® 28, the most widely used metallic material for evaporator tubes in the manufacture of phosphoric acid by the ”wet” method, is our solution for this application.
Sulfuric acid solution
For highly concentrated sulfuric acid at high temperatures, Alleima® SX provides excellent corrosion protection up to 266°F (130° C). For lower concentrations, which may include impurities or applications where the cooling media contains chlorides, Sanicro® 28 or Sanicro® 32Cu (Alloy 20) will offer the best resistance.
Bimetallic solutions
We’ve developed bimetallic tube solutions that offer zirconiumlevel performance at an affordable price. The inner tube is made of zirconium and an outer tube is made with Alleima® 2RE10, Alleima® 2RE69 or a material of your choice.
