Food Processing Applications – Stainless Steel Tube & Pipe & sheet
Food and beverage production requires hygienic materials that are easy to clean and resistant to corrosion, chemicals, and temperature changes. Stainless steel tubes and pipes are the backbone of modern dairies, beverage plants, breweries, and food processing factories, from sanitary process piping to utility lines and equipment structures.
YES Stainless International supplies welded sanitary tube, industrial stainless steel pipe, and seamless stainless steel tube for food contact and non-food contact services. Our products are available in food-grade stainless steel, such as 304/304L and 316/316L, manufactured according to international standards, including ASTM A270, A249, A269, A213, A312, and A554, with EN 10204 3.1 Mill Test Certificates available for each order.
Main Food & Beverage Applications
- Hygienic process piping for dairy, beverage, brewery, and sauce production
- Utility piping for steam, hot water, chilled water, and compressed air
- CIP/SIP cleaning and sterilization lines
- Heat exchanger tubes for heating and cooling food products
- Equipment frames, supports, platforms, and conveyor structures
- Instrumentation and sampling lines
1. Hygienic Process Piping – Sanitary Stainless Steel Tube
Sanitary process lines are where stainless steel tubes are in direct contact with food and beverage products. Typical applications include:
- Milk, yogurt, cream, and other dairy products
- Juices, tea, coffee, soft drinks, and syrups
- Beer, wine, and other fermented beverages
- Soy sauce, vinegar, liquid seasonings, and sauces
- Edible oils, chocolate, and high-viscosity liquids
For these lines, food manufacturers require the sanitary stainless steel tube with:
- Smooth internal surface (low roughness, often Ra ≤ 0.8 μm) to minimize product retention and bacterial growth
- High-quality welds that are flush and fully penetrated, suitable for orbital welding
- Easy-to-clean system design, compatible with CIP and SIP procedures
- Standardized sanitary fittings, such as clamp, ferrule, and hygienic elbows and tees
Typical grades
- AISI 304 / 304L – widely used for dairy and beverage lines
- AISI 316 / 316L – preferred for higher chloride content, acidic products, and aggressive cleaning chemicals
Typical ASTM reference
- ASTM A270 – Sanitary stainless steel tubing for dairy and food industry service
2. Utility Piping – Steam, Hot Water, Chilled Water & Gases
Utility piping does not always come into direct contact with food, but it is essential for heating, cooling, and operating the plant:
- Steam lines for sterilization, heating, and CIP/SIP systems
- Hot and cold water lines for process and cleaning
- Chilled water and glycol lines for cooling tanks, mixers, and jacketed vessels
- Compressed air and inert gas lines (nitrogen, CO₂) for actuation and packaging
For these utilities, food processors typically use industrial stainless steel pipe or tube. The surface finish requirement is usually less stringent than that of a sanitary tube, but corrosion resistance, pressure rating, and weldability remain critical.
Typical grades
- 304 / 304L – standard for many water and air systems
- 316 / 316L – recommended for higher chloride content or more aggressive conditions
Typical ASTM references
3. CIP/SIP Cleaning & Sterilization Lines
CIP (Cleaning-In-Place) and SIP (Sterilization-In-Place) systems circulate alkaline and acidic cleaning solutions, followed by hot water or steam, through the production lines. These circuits include:
- CIP supply and return lines for caustic and acid solutions
- Hot water or steam lines for final rinsing and sterilization
- Recovery or drain lines for used cleaning fluids
Although CIP and SIP lines may not carry food products directly, the chemicals and high temperatures require stainless steel that:
- Resist corrosion from caustic soda, acids, and disinfectants
- Withstand frequent thermal cycling
- Maintain cleanable and non-reactive surfaces
In many plants, the same 304L / 316L grades are used for both process and CIP/SIP lines to simplify maintenance and spare parts.
Typical ASTM references
4. Heat Exchanger Tubes – Heating & Cooling of Food Products
Heat exchangers are commonly used in food plants for pasteurization, sterilization, cooling, and temperature control. Stainless steel tubes are found in:
- Tubular heat exchangers for milk, juices, and sauces
- Shell-and-tube heat exchangers for product heating/cooling or CIP fluids
- Pre-heaters and coolers in beverage and brewery lines
On the product side, tubes must be hygienic, corrosion-resistant, and compatible with cleaning chemicals. On the utility side, they must handle hot water, steam, chilled water, or glycol under pressure.
Typical grades
- 304 / 304L – general food and beverage heating/cooling
- 316 / 316L – more aggressive products or higher chloride content
Typical ASTM references
- ASTM A213 – Seamless austenitic stainless steel heat exchanger tubes
- ASTM A269 – General service tubing used in lower-pressure heat exchangers
5. Stainless Steel Sheet in Food Processing Kitchens
Stainless steel is the default material for professional kitchens because it stays clean, resists corrosion, and tolerates heat and impact. In food processing environments, it is used for contact surfaces, structural frames, and utility lines where hygiene and uptime matter.
- Sinks and wash stations
- Worktops and prep counters
- Splashbacks and wall cladding
- Shelving, racks, trolleys, and cabinets
- Hoods, ducting, and machine enclosures
- Frames and supports
Typical grades and finishes
- 304 / 304L: The standard choice for sinks, counters, and general kitchen equipment.
- 316 / 316L: Use near brine, acidic foods, coastal air, or aggressive cleaners for higher corrosion resistance.
- 430: Suitable for dry interiors and decorative cladding where corrosion risk is lower.
- Common finishes: 2B or BA for cleanability inside equipment, No.4 or hairline on visible counters and panels to mask scratches; electropolish or defined Ra targets when hygiene validation is required.
