Inconel Catalytic Reactors
Roben Mfg, Inc. fabricates Inconel catalytic reactors for extreme temperature and highly corrosive chemical processing applications. Our Inconel reactor vessels deliver exceptional performance where standard stainless steels cannot survive, maintaining structural integrity and corrosion resistance at temperatures exceeding 2000°F.
Why Inconel for Catalytic Reactors?
Inconel nickel-chromium superalloys provide unmatched performance in high-temperature oxidizing environments, resisting creep, thermal fatigue, and aggressive chemical attack. These materials maintain their strength at temperatures where other alloys fail, making them essential for steam reforming, high-temperature oxidation, and processes involving sulfur compounds or chlorides at elevated temperatures.

Frequently Asked Questions
1. What Inconel grades are suitable for catalytic reactors?
Inconel 600 offers excellent high-temperature oxidation resistance for general service. Inconel 625 provides superior corrosion resistance, including resistance to pitting and crevice corrosion. Inconel 718 delivers the highest strength for applications requiring pressure containment at extreme temperatures.
2. What are the maximum operating temperatures for Inconel reactors?
Inconel alloys maintain useful strength to approximately 2000°F (1090°C), with oxidation resistance to even higher temperatures. Actual design temperature depends on the specific grade, pressure requirements, and required service life. Our engineering team optimizes material selection for your operating conditions.
3. How do you fabricate Inconel catalytic reactors?
Inconel requires specialized welding procedures using matching filler metals and controlled heat input. We employ qualified welders with specific Inconel certifications and perform appropriate pre-heat and post-weld heat treatments. All welds undergo rigorous NDE including radiographic and ultrasonic examination.
