ASTM A270 3A TP304 BA Stainless Steel Sanitary Seamless Tube For Sugar Industry

ASTM A270 3A TP304 Bright Annealed Stainless Steel Sanitary Seamless Tube For Sugar Industry

The ASTM A270 TP304 Bright Annealed Stainless Steel Sanitary Seamless Tube is a hollow, cylindrical product manufactured to the stringent standards of ASTM A270, specifically for sanitary applications. It is made from stainless steel 304, produced through a seamless manufacturing process (extrusion), and finished with a Bright Annealed (BA) surface. This combination results in a tube that offers exceptional corrosion resistance, high purity, and an ultrasmooth, bright surface finish, making it ideal for industries where cleanliness and sterility are paramount, such as food processing, dairy, beverage, pharmaceutical, and biotechnology. YUHONG GROUP has abundant manufacturing experience of ASTM A270 TP304 stainless steel sanitary tubes with excellent quality. The outer diameter ranges from 6.35mm to 152.4mm and the wall thickness is typically produced from 0.5mm to 3.4mm. Our sanitary tubes are widely applied in food grade applications, beverage industry, sugar refinery, distiller, evaporator, refrigeration system, heat exchanger, and so on.

Chemical Composition(%) of ASTM A270 TP304:

Different Surface Finishes:

1. Bright Annealed (BA): This is a smooth, bright, reflective finish achieved by annealing in a protective atmosphere. It is the standard finish for many pharmaceutical and high-purity applications.

2. Mechanical Polish (MP): This finish is achieved by mechanically grinding and polishing the tube surface. It is specified by the grit size of the abrasive used.

• 150-180 Grit: A general-purpose sanitary finish. The interior is typically mechanically polished to this level.
• 240-320 Grit: A finer finish used in applications requiring even lower surface roughness to prevent bacterial adhesion.

3. Electropolished (EP): This is an electrochemical process that removes a thin layer of material from the surface. It produces an ultrasmooth, non-stick, and highly passive surface. It offers the highest level of cleanability and corrosion resistance. Often applied after mechanical polishing.

Key Advantages and Features:

• Superior Corrosion Resistance
• Hygienic and Easy to Clean
• Excellent Mechanical Integrity
• Good Formability and Weldability
• Durability and Long Service Life

Different Applications of SS304 Sanitary Tubes:

• Food and Beverage Industry: Transporting milk, beer, wine, juices, edible oils, and other liquid food products.
• Dairy Industry: Used extensively in pipelines for pasteurizers, separators, homogenizers, and storage tanks for milk and cream.
• Pharmaceutical and Biotechnology: Used for handling purified water (WFI - Water For Injection), process streams for active pharmaceutical ingredients, buffer solutions, and in clean steam distribution systems.
• Cosmetics Industry: Transporting lotions, creams, and other personal care products where hygiene is critical.
• Dairy Farms: Used in milking machines and transfer lines.
• Breweries and Wineries: Used in brewhouses, fermenters, bright beer tanks, and transfer lines.
