2. Key Applications

• Chemical & Petrochemical: Corrosion-resistant piping for acids, chlorides, and aggressive media.

• Marine Environments: Seawater pipelines, offshore platforms, and desalination systems.

• Food & Beverage: Hygienic fluid transport due to non-reactive surface and cleanability.

• Pharmaceutical: High-purity process lines requiring resistance to sterilization and chemicals.

• Power Plants: Heat exchangers, condensers, and superheater tubes in corrosive/thermal conditions.

 

3. Manufacturing Standards

• Complies with EN 10216-5: Seamless steel tubes for pressure purposes at elevated temperatures.

• Equivalent to ASTM A312/A312M TP316L and ASME SA312 for austenitic stainless steel pipes.

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

 

4. Testing & Certification

• Hydrostatic Testing: Conducted per EN ISO 3458 to verify pressure integrity.

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

• Chemical Analysis: Verified via optical emission spectrometry (OES).

• Mechanical Testing: Tensile, hardness (HV), and impact testing (optional for low temps).

• Certifications: EN 10204 3.1/3.2 Mill Test Reports (MTRs), ISO 9001, and PED compliance.

 

5. Advantages

• Superior Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich environments.

• High-Temperature Stability: Maintains mechanical properties up to 400°C (750°F).

• Hygienic Surface: Ideal for sanitary applications with smooth, easy-to-clean finishes.

• Weldability: Compatible with TIG, MIG, and plasma welding methods without post-weld treatment.

• Low-Temperature Toughness: Suitable for cryogenic applications down to -196°C (-320°F).

 

6. Surface Finish & Dimensions

• Surface: Pickled, polished, or blasted finishes (Ra ≤0.8 µm for sanitary use).

• Sizes: Outer diameter 6-762 mm (0.24-30"), wall thickness 1-50 mm (0.039-1.97").
