Hastelloy and Other Nickel Alloys Agitated Vessels

Nickel alloy agitated vessels utilize high-performance alloys such as Hastelloy, Inconel, and Monel for exceptional corrosion resistance in the most demanding chemical environments. These vessels provide reliable mixing capability for processes involving aggressive acids, high temperatures, or combinations that would destroy other materials.

Why Choose Hastelloy and Other Nickel Alloys for Agitated Vessels?

Nickel alloys are essential for agitated vessels handling highly corrosive chemicals where stainless steels and other common materials cannot perform. The exceptional corrosion resistance of nickel alloys enables processing of aggressive acids, chlorinated compounds, and high-temperature oxidizing environments that require premium materials for reliable operation.

Frequently Asked Questions (FAQs)

How do you select the appropriate nickel alloy?

Alloy selection depends on specific corrosive environment. Hastelloy C-276 provides broad resistance to oxidizing and reducing conditions. Hastelloy B-type alloys excel in reducing acids like HCl. Inconel alloys suit high-temperature oxidizing service. Monel handles HF acid and seawater. We recommend alloys based on complete process chemistry analysis.

What agitator materials are used with nickel alloy vessels?

Agitator wetted parts are typically fabricated from the same alloy as the vessel for uniform corrosion resistance. Shaft sealing components are selected for chemical compatibility. In some cases, different alloys may be optimal for specific components. We design complete agitation systems with appropriate materials throughout.

Are nickel alloy vessels cost-effective?

Despite higher material costs, nickel alloy vessels often provide superior economics for aggressive chemical service through extended service life, reduced maintenance, and reliable operation. The alternative—frequent replacement of less resistant materials—typically costs more over time. We provide life-cycle cost analysis to support material decisions.
