Precision Stainless Steel Welded Tubing for Capillary Components
Why 304 Stainless Steel for Food & Beverage?
304 stainless steel capillary tubes are the material of choice for food and beverage processing equipment. With excellent corrosion resistance, easy cleanability, and compliance with FDA 21 CFR 177.2600 for food contact, 304 stainless steel ensures product safety, process reliability, and regulatory compliance.
Key Properties for Food Applications
| Property | Benefit |
|---|---|
| Corrosion resistance | Resists food acids, cleaning chemicals, and water |
| Easy cleanability | Smooth surface prevents bacterial adhesion |
| FDA compliant | Safe for food contact applications |
| Temperature resistance | Withstands pasteurization, sterilization, and freezing |
| Formability | Easy to bend, flare, and form for custom configurations |
| Cost-effective | Lower cost than 316 for general food applications |
