316L Stainless Steel Sanitary Tubing | Corrosion Resistant Hygienic Tube
PuroFlow 316L stainless steel sanitary tubing, ideal for corrosive sanitary process lines. Available in standard sizes, polished finish and welded construction.
Description
PuroFlow produces 316L stainless steel sanitary tubing and also offers 316 stainless steel sanitary tubing grades as an option.
This sanitary tubing belongs to sanitary stainless steel tubing and is also commonly called stainless sanitary tubing or hygienic stainless steel tube. Its corrosion resistance is superior to that of 304 sanitary tubing under chloride-containing cleaning media and acidic material conditions. It is widely used in sanitary fluid transfer systems in food and beverage, pharmaceutical, dairy, fine chemical, and other industries, and supports CIP clean-in-place cleaning.

Material Grades and Corrosion Resistance Differences
316L: Low-carbon version, with stronger intergranular corrosion resistance, suitable for frequent high-temperature disinfection and acid cleaning conditions;
316: Conventional carbon content, more cost-effective, suitable for conventional sanitary fluid conditions.
The tubing is polished inside and outside, and the weld seam is ground flat without dead corners to reduce microbial adhesion.
Typical Applications
Pharmaceutical and biopharmaceutical production lines
Dairy, juice, and brewing production lines
Fine chemical acidic material transfer
Seawater and disinfectant-containing cleaning circuits
Purified water and ultrapure water transfer lines
Frequently Asked Questions (FAQ)
How to choose between 316L sanitary tubing and 304 sanitary tubing?
316L stainless steel sanitary tubing has stronger resistance to chloride ion and acidic medium corrosion and is preferred for systems whose cleaning process contains bleach or nitric acid pickling; for ordinary food and clean water transfer scenarios, please refer to our 304 stainless steel sanitary tubing page.
Can you provide 316L sanitary tubing in 2″, 4″, and 8″ specifications?
Standard stock covers 2″ 316L stainless steel sanitary tubing and 4″ 316L sanitary tubing; 8″ 316L sanitary tubing is custom-produced. You are welcome to provide drawings for a quotation.
Can the surface polishing grade of 316L sanitary tubing be customized?
Multiple Ra surface finish levels can be customized, and inspection reports can be provided to meet FDA and 3A sanitary regulatory requirements.
