Safurex STAINLESS STEEL

Technology:

Special duplex stainless steel

Developed together with Sandvik

Corrosion resistant in oxygen-free carbamate environment

Better mechanical strength as compared to fully austenitic stainless steels



Advantages:

Zero oxygen: intrinsically safe plant

Lower corrosion rates: longer life time of equipment, less maintenance cost

No stress corrosion cracking, no crevice corrosion

Improved weld ability; higher strength: Simplified equipment design, reduction of piping cost

Zero oxygen: less ammonia emissions

STAMICARBON GRANULATION TECHNOLOGY


STAMICARBON GRANULATIONTECHNOLOGY

Advantages:

Excellent product quality

Less formaldehyde consumptions: reduces variable production cost

Long uninterrupted run length: reduces operational cost; minimizes production loss resulting from cleaning operations

Low opacity at outlet of granulator stack

Low urea solution recycle: reduces operational cost
