Stainless Steel Heat Treated Jacketed Reactors
Roben Mfg, Inc. fabricates stainless steel heat treated jacketed reactors for applications requiring superior corrosion resistance and material purity. Our stainless steel jacketed vessels deliver reliable performance in aggressive chemical environments while maintaining the surface quality essential for pharmaceutical, food, and specialty chemical manufacturing.
Why Stainless Steel for Heat Treated Jacketed Reactors?
Stainless steel alloys provide the corrosion resistance, cleanability, and mechanical properties required for demanding jacketed reactor applications. These materials resist attack from acids, bases, and organic compounds while maintaining structural integrity through repeated thermal cycling. The passive oxide layer inherent to stainless steel prevents product contamination and enables thorough cleaning between batches.

Frequently Asked Questions
1. What stainless steel grades are best for jacketed reactors?
Grade selection depends on process chemistry and temperature requirements. 304/304L suits most general applications. 316/316L provides better resistance to chlorides and acids, making it standard for pharmaceutical use. 317L and duplex grades address severe corrosion or high-strength requirements.
2. How does heat treatment affect stainless steel properties?
Post-weld heat treatment (PWHT) relieves residual stresses from welding, improving corrosion resistance and dimensional stability. Solution annealing restores optimal microstructure after welding or forming. We apply appropriate heat treatments based on material grade and service requirements.
3. What surface finishes are available for stainless steel reactors?
We provide mechanical polishing from #4 finish through mirror polish, electropolishing for maximum corrosion resistance and cleanability, and passivation treatments. Pharmaceutical applications typically require electropolished surfaces meeting ASME BPE standards with documented Ra values.
