SUS304 stainless steel pipe for food processing equipment

What is SUS304 stainless steel pipe used for in food processing equipment?

SUS304 stainless steel pipe for food processing is a hygienic, corrosion-resistant, and durable tubing (made with 18% chromium, 8% nickel) used for safely transporting liquids and ingredients, preventing bacterial growth with its smooth surface, ensuring food safety, and standing up to cleaning in breweries, dairies, and general food/beverage production. Its excellent corrosion resistance and non-porous finish make it easy to clean and sterilize, preventing contamination and extending equipment life.
