Bright Annealed Polished Seamless Stainless Steel Tube 304 6-813mm OD for Sanitary

This bright annealed polished seamless stainless steel tube is manufactured from 304 (1.4301) austenitic stainless steel and finished to a mirror-bright, hygienic surface ideal for sanitary and dairy applications. Bright annealing is performed in a controlled protective atmosphere, producing a clean, oxidation-free surface without the need for subsequent pickling. The result is a smooth, lustrous finish with low surface roughness that resists bacterial adhesion, simplifies cleaning, and enhances both appearance and corrosion resistance. The seamless construction eliminates weld seams and internal crevices where contaminants could accumulate. Available in outer diameters from 6 mm to 813 mm with wall thicknesses from 0.5 mm to 60 mm, the tube is supplied in standard and custom cut lengths to suit hygienic process lines.

• Bright Annealed Finish: controlled atmosphere annealing yields a clean, oxidation-free surface.
• Mirror Polish: low surface roughness resists bacterial adhesion and eases cleaning.
• Hygienic Seamless Bore: no weld seams or crevices where contaminants could collect.
• 304 Corrosion Resistance: reliable performance in food and dairy contact applications.
• Aesthetic Appearance: bright finish suits exposed and architectural applications.
• Full NDT Verification: ultrasonic, eddy current, and hydrostatic testing on every tube.

The bright annealed polished 304 seamless stainless steel tube is widely used in dairy processing, beverage production, food handling, and pharmaceutical applications where hygienic conditions are essential. Its mirror-smooth interior supports clean-in-place systems and reduces the risk of product contamination. The bright finish also makes it a popular choice for exposed architectural handrails, furniture, and decorative tubing where appearance matters alongside corrosion resistance. In sanitary process lines, the tube reliably carries milk, water, syrups, and other food-grade fluids while resisting the cleaning chemicals used in daily sanitation. Its combination of hygienic finish, corrosion resistance, and aesthetic appeal makes it a versatile solution across food, beverage, and light industrial applications.

Each tube is protected with plastic end caps and wrapped in clean film before being bundled with steel straps or packed into seaworthy wooden cases. This protects the polished surface and prevents contamination during storage and transport. Complete mill test certificates, including chemical composition, mechanical properties, and NDT reports, accompany every shipment. Production is carried out under an ISO 9001:2015 certified quality management system, with optional third-party inspection by SGS or BV to support sanitary and regulatory compliance.
