Key features of 304 stainless steel polished pipe
Main alloy: 18% chromium (Cr), 8% nickel (Ni), providing corrosion resistance.
Certification standard: ASTM A270 (American standard), GB4806.9-2016 (Chinese food grade stainless steel standard).
Corrosion resistance
Passivation film: Chromium reacts with oxygen to form a chromium oxide layer to resist acidic/alkaline foods (such as lemon juice, detergents).
Surface treatment
Polishing process: mechanical or electrolytic polishing, surface roughness (Ra) ≤ 0.4μm, reducing microbial attachment.

Application of 304 stainless steel pipe
Food processing: liquid food delivery pipelines (milk, juice), fermentation tanks, sterilization equipment.
Beverage industry: beer, carbonated beverage production line, filling system.
Pharmaceutical equipment: purified water pipeline, liquid medicine delivery system.
Kitchen facilities: commercial kitchen worktops, sinks, refrigeration equipment brackets.

Notes
Certification verification: Material reports (such as SGS testing) and food-grade certification marks must be checked when purchasing.
Environmental adaptability:
Ordinary environment: 304 is sufficient.
Highly corrosive environment (coastal, high salt): It is recommended to upgrade to 316 stainless steel (containing 2-3% molybdenum).
Processing technology: The weld needs to be polished after welding to ensure surface consistency and avoid sanitary dead corners.
