2. Key Applications

• Chemical Processing: Corrosion-resistant piping for acids, alkalis, and aggressive chemicals.

• Food & Dairy Industry: Hygienic tubing for sanitary fluid transport and processing.

• Pharmaceuticals: High-purity systems requiring non-reactive and sterilizable surfaces.

• Heat Exchangers: Tubes for condensers, boilers, and thermal systems in corrosive environments.

• Architecture: Decorative and structural components in harsh atmospheric conditions.

 

3. Manufacturing Standards

• Complies with DIN 17456: Seamless austenitic stainless steel tubes for general corrosion resistance.

• Equivalent to EN 10216-5 and ASTM A312/A312M TP304/304L for material performance.

• Meets PED 2014/68/EU (Pressure Equipment Directive) for critical pressure applications.

 

4. Testing & Certification

• Hydrostatic Testing: Pressure-tested to ensure integrity under operational conditions.

• Non-Destructive Testing (NDT): Eddy current, ultrasonic (UT), or dye penetrant inspection.

• Chemical Analysis: Verified via optical emission spectrometry (OES) or X-ray fluorescence (XRF).

• Mechanical Testing: Tensile, hardness (HV), and impact tests (optional for low-temperature use).

• Certifications: DIN 17456-compliant Mill Test Reports (MTRs), ISO 9001, and PED documentation.

 

5. Advantages

• Exceptional Corrosion Resistance: Resists oxidation, pitting, and stress corrosion cracking in acidic/chloride environments.

• High-Temperature Suitability: Maintains strength and stability up to 400°C (750°F).

• Hygienic Design: Smooth surface finish ideal for cleanability in food and pharmaceutical applications.

• Formability & Weldability: Easily fabricated using standard methods (TIG, MIG welding) without post-treatment.

• Aesthetic Durability: Retains appearance and structural integrity in decorative architectural uses.

 

6. Surface Finish & Dimensions

• Surface: Pickled, polished, or bright-annealed finishes (Ra ≤0.8 µm for sanitary applications).

• Sizes: Outer diameter 6-426 mm (0.24-16.8"), wall thickness 1-20 mm (0.039-0.79").
