2205 Duplex Stainless Steel Pipe is a premium-grade tubular product manufactured from duplex stainless steel with a balanced microstructure of austenite and ferrite. This composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments. The material is widely recognized under international standards such as ASTM A790, ASME SA790, and EN 10216-5.
At Jiangsu Cunrui Metal Products Co., Ltd., we supply 2205 Duplex Stainless Steel Tube with full mill test certificates (MTC), third-party inspection reports, and complete traceability to ensure product reliability. With high yield strength, outstanding toughness, and stable performance in harsh service conditions, our pipes are suitable for demanding industries such as marine engineering, chemical processing, and energy systems.
Key Features & Advantages
Corrosion Resistance: Superior to 316L stainless steel in seawater and acidic environments.
High Strength: Nearly twice the yield strength of conventional stainless steels.
Excellent Weldability & Formability: Suitable for fabrication without sacrificing mechanical integrity.
Cost Efficiency: Longer service life reduces maintenance and replacement costs.
Global Standards Compliance: Produced in accordance with ASTM, ASME, EN, and ISO specifications.
Applications
The 2205 Duplex Stainless Steel Pipe is widely used in industries where both strength and corrosion resistance are critical:
Offshore platforms and subsea pipelines
Pressure vessels, chemical storage tanks, and heat exchangers
Pulp and paper processing equipment
Oil & gas transportation systems
Structural applications in marine environments
Desalination plants and water treatment facilities
