Hastelloy and Other Nickel Alloys Jacketed Vessels

Nickel alloy jacketed vessels utilize high-performance alloys such as Hastelloy, Inconel, and Monel for exceptional corrosion resistance and high-temperature capability. These vessels provide temperature-controlled processing for the most demanding chemical environments where other materials would fail.

Why Choose Hastelloy and Other Nickel Alloys for Jacketed Vessels?

Nickel alloys are essential for jacketed vessels handling highly corrosive chemicals at controlled temperatures. The exceptional corrosion resistance of nickel alloys enables processing of aggressive acids, chlorinated compounds, and high-temperature oxidizing environments while jacket systems maintain required temperatures.

Hastelloy and Other Nickel Alloys Jacketed Vessel Applications

Common applications include:

• Strong acid processing
• High-temperature reactions
• Chlorinated compound handling
• Fluorine and HF service
• Oxidizing environments
• Specialty chemical production

Frequently Asked Questions (FAQs)

Is the jacket typically nickel alloy when the vessel is?

Not necessarily. Jacket material is selected based on jacket media compatibility. A Hastelloy process vessel might have a stainless steel jacket if the heating/cooling media is steam or water. Full alloy construction is used when jacket-side conditions also require corrosion resistance.

How does nickel alloy affect heat transfer?

Nickel alloys have lower thermal conductivity than stainless steel, which may slightly reduce heat transfer rates. Jacket design compensates through adequate surface area. The thermal properties are well understood and easily accommodated in design. Corrosion resistance benefits far outweigh minor thermal conductivity differences.

What welding requirements apply to nickel alloy vessels?

Nickel alloy welding requires clean conditions, matching filler metals, and proper heat input control. Welders must be qualified for specific alloy procedures. Post-weld heat treatment may be required depending on alloy and service conditions. Our welders are fully qualified for nickel alloy fabrication.
