Product Description

304 Annealed BA Surface Precision Tube (Φ25×1.5mm) - Hygienic Corrosion Resistance for Food & Beverage Piping

GMP-Compliant Fluid Transfer Solution

Engineered for critical sanitary applications, our 304 stainless steel precision tubes with Bright Annealed (BA) surface finish deliver uncompromising corrosion resistance and microbial control in food/beverage processing systems. The Φ25×1.5mm dimension provides optimal flow dynamics for dairy, brewing, and pharmaceutical transfer lines while exceeding 3-A Sanitary Standards and FDA CFR 21 requirements.

 

Key Performance Attributes

1. Premium Material Composition

• Grade 304 Stainless Steel: 18% Cr / 8% Ni alloy for chloride resistance

• Annealed Condition:

  • Hardness: 150-200 HV (optimal for orbital welding)

  • Elongation: ≥40% (superior formability)

2. Bright Annealed (BA) Surface

• Ra ≤ 0.4 μm: Mirror finish prevents bacterial adhesion

• Passivation: Post-anneal nitric acid treatment enhances CrO2 layer

• Zero Contamination: Seamless cold-drawn process eliminates scaling

3. Precision Dimensional Control

Parameter	Tolerance	Benefit
OD: 25mm	±0.05mm	Leak-proof fitting seals
Wall: 1.5mm	±0.03mm	Burst pressure >120 bar
Straightness	≤0.3mm/m	Vibration-free installation
