CSX™ for Sulfuric Acid Applications
Clark Solutions CSX™ is a High Silicon Stainless Steel (HSSS) developed to provide high corrosion resistance over a wide range of sulfuric acid temperatures and concentrations while maintaining its structural properties under demanding process conditions. Its performance is based on the formation of a highly resistant passive silicon oxide layer on the material surface. This characteristic provides high resistance to concentrated sulfuric acid as well as enhanced protection against corrosion, pitting, and erosion, making CSX™ particularly suitable for equipment and systems exposed to highly corrosive environments.
Benefits of CSX™
High Corrosion Resistance
Developed to operate across different sulfuric acid concentrations and temperatures, providing high resistance under typical process conditions.
Lower Equipment Weight
The material's high resistance allows thinner wall thicknesses, reducing equipment weight as well as the requirements for civil foundations, assembly, and maintenance.
Greater Operational Safety
Welded construction reduces the number of flanges and, consequently, potential acid leakage points.
Better Acid Product Quality
Low corrosion rates contribute to reducing iron contamination in the final acid product.
Resistance to Erosion and Pitting
The passive layer formed on the CSX™ surface provides additional protection against relevant degradation mechanisms, especially in piping systems and fittings.
Versatility of Applications
CSX™ can be applied to piping and fittings, mist eliminators, towers and pump tanks, acid distributors, and acid coolers.
Applications
Piping & Fittings • Mist Eliminators • Towers & Pump Tanks • Acid Distributors • Acid Coolers
