Sanitary Grade 304 Stainless Steel Seamless Tube Food Beverage Dairy Hygienic Surface

Sanitary grade 304 stainless steel seamless tube is produced for food, beverage, dairy and pharmaceutical lines where hygiene, cleanability and product purity are critical. The tube is cold drawn seamless and finished with a bright polished internal surface that meets a roughness average of 0.8 micrometre or better, leaving no crevices or weld seams where bacteria and residues can collect. This smooth, passive surface supports effective clean in place procedures and helps processors meet food safety and regulatory requirements.

The 304 austenitic chemistry provides good corrosion resistance to the mild acids, dairy products, sugars and cleaning agents typically found in food processing, and the seamless wall maintains a uniform bore that supports consistent flow and reliable cleaning. Tubes are eddy current tested, cleaned and passivated, and can be supplied to ASTM A270 or ASTM A269 in a range of diameters and wall thicknesses. Mill test certificates and third party inspection reports accompany every shipment, reinforcing the confidence that food and beverage manufacturers need in their raw materials.

• Sanitary Food Grade: Designed for hygienic lines in food, beverage and dairy processing where cleanliness and product purity are essential.
• Hygienic Bright Polished Bore: Internal roughness average of 0.8 micrometre or better prevents residue build up and supports effective clean in place.
• Seamless Smooth Wall: No weld seam or internal bead, eliminating crevices that trap bacteria and simplifying sanitation.
• Corrosion Resistant: 304 austenitic chemistry resists mild acids, sugars, dairy products and common cleaning chemicals.
• Weldable and Fabricable: The low carbon friendly chemistry allows reliable welding, bending and forming during equipment fabrication.
• Tested and Traceable: Eddy current tested, cleaned and passivated, supplied with mill test certificates for full traceability.

This sanitary seamless tube is used throughout food and beverage plants for milk, juice, beer, syrup and ingredient transfer, in dairy processing and cheese making, in pharmaceutical and biotech fluid systems, and in cosmetic and personal care production. It is also suited to high purity water and clean steam lines, fermentation equipment and hygienic processing skids. Its bright polished bore, smooth seamless wall and reliable traceability make it a dependable material for processors who must meet strict hygiene, quality and regulatory standards while keeping cleaning costs low.

Tubes are cleaned, passivated and dried, capped at both ends, wrapped in protective sleeving and packed in strong wooden cases to keep the bright bore free from damage and contamination. Each bundle is labelled with grade, dimension, heat number and quantity for full traceability. We supply mill test certificates, internal surface roughness reports and third party inspection on request, and our ISO 9001 and CE certified process ensures consistent hygienic quality. Cutting, bending, passivation and custom finishing are available to suit your processing line.
