Stainless Steel (304, 316L, and Other Grades) Jacketed Vessels
Stainless steel jacketed vessels utilize austenitic stainless steel grades for both process vessel and jacket construction, providing excellent corrosion resistance, cleanability, and durability. These vessels are the standard choice for pharmaceutical, food, chemical, and other applications requiring sanitary construction and resistance to corrosive environments.
Why Choose Stainless Steel (304, 316L, and Other Grades) for Jacketed Vessels?
Stainless steel is the most widely specified material for jacketed vessels due to its excellent combination of corrosion resistance, thermal conductivity, fabricability, and sanitary characteristics. Grades from economical 304 to highly corrosion-resistant 316L and duplex provide options for virtually any process while meeting regulatory requirements.

Frequently Asked Questions (FAQs)
Should the vessel and jacket use the same stainless grade?
Not necessarily. The process vessel grade is selected for process compatibility, while the jacket often uses a less expensive grade since it contacts only heating/cooling media. A 316L process vessel might have a 304L jacket for steam or water service, optimizing cost while meeting process requirements.
What surface finishes are available for stainless jacketed vessels?
Finishes range from mill finish for industrial applications to electropolish (Ra < 15 microinch) for pharmaceutical and biotech. Standard options include #4 polish (180 grit), 2B mill, sanitary polish (Ra 20-32 microinch), and electropolish. Finish selection depends on cleanability and regulatory requirements.
How does stainless steel perform with steam heating?
Stainless steel performs excellently with steam heating. Its corrosion resistance handles steam condensate, while good thermal conductivity provides efficient heat transfer. Jacket design accommodates thermal expansion. Stainless steel jackets are the standard for steam-heated vessels in most industries.
