Available Types of 2205 Stainless Steel Pipes
Huaxiao Metal supplies different types of duplex stainless steel pipes for industrial applications.
2205 Seamless Stainless Steel Pipe
Manufactured through hot extrusion or cold drawing processes, seamless pipes provide excellent pressure resistance and structural strength.
Typical applications:
High-pressure pipelines
Oil & gas transportation
Chemical equipment
2205 Welded Stainless Steel Pipe
Welded pipes are produced by forming and welding stainless steel plates or coils.
Advantages:
Lower production cost
Wide size range
Suitable for structural and fluid transportation systems
Key Advantages of 2205 Steel Pipe
Extreme Pressure Handling: The high yield strength (≥450 MPa) allows for reduced wall thickness, leading to significant weight savings (up to 30%) and lower transportation costs.
Superior Corrosion Resistance: With a PREN of 32-35, our 2205 pipes outperform 316L in sour gas (H2S) and high-chloride environments.
Excellent Weldability: Unlike earlier duplex grades, 2205 has balanced austenite and ferrite phases, providing excellent weldability and toughness.
100% Quality Tested: Every 2205 pipe undergoes Hydrostatic Testing, Eddy Current Testing, and PMI Inspection before delivery.
Equivalent Grades of 2205 Stainless Steel Pipe
2205 duplex stainless steel pipe is identified under several international material standards.
| Standard | Grade |
|---|---|
| UNS | S31803 / S32205 |
| EN | 1.4462 |
| ASTM | Duplex 2205 |
| Common Name | 2205 |
UNS designation S22053 is sometimes mentioned in earlier duplex stainless steel specifications, but modern industry standards primarily use S32205.
If you are unsure which material is right for your project, Huaxiao Metal’s engineers can help you select the appropriate stainless steel grade.
Applications of 2205 Stainless Steel Pipe

FAQ – 2205 Duplex Stainless Steel Pipe
What is the recommended welding filler for 2205 pipe?
We recommend using E2209 filler metal. It is over-alloyed with nitrogen and nickel to ensure the weld maintains the correct 50/50 phase balance for maximum corrosion resistance.
What is the difference between ASTM A789 and A790?
ASTM A789 covers duplex stainless steel tubing for general service (heat exchangers, etc.), while A790 specifically covers seamless and welded duplex pipes intended for high-temperature and corrosive services.
Can 2205 pipe be used in sub-zero temperatures?
Yes, 2205 has good impact toughness down to -50°C (-58°F). However, for cryogenic service below this temperature, austenitic grades like 304L or 316L are preferred.
What is 2205 stainless steel pipe used for?
2205 stainless steel pipes are widely used in oil and gas pipelines, chemical processing systems, marine engineering, and desalination plants.
Is 2205 better than 316 stainless steel pipe?
Yes. Duplex 2205 provides higher strength and better resistance to chloride corrosion compared with 316 stainless steel.
Can 2205 stainless steel pipes be welded?
Yes. Duplex 2205 stainless steel has good weldability, but proper welding procedures should be followed to maintain the correct microstructure.
