2205 Duplex Stainless Steel Pipe combines high mechanical strength with excellent resistance to pitting, stress corrosion cracking, and chloride attack. Compared with conventional austenitic stainless steels, it provides enhanced durability and long-term performance in demanding service environments.
Widely used in offshore engineering, chemical processing equipment, marine systems, and industrial applications requiring both strength and corrosion resistance.
The 2205 duplex stainless steel pipe is a nitrogen-enhanced duplex alloy pipe engineered for fluid handling in harsh chemical and marine environments. Featuring a balanced dual-phase microstructure composed of roughly equal proportions of ferrite and austenite, 2205 duplex steel pipe delivers nearly twice the yield strength of standard austenitic pipes like 304 and 316 stainless steel.
Compared to traditional austenitic alloy pipes, 2205 duplex stainless steel pipe offers superior resistance to localized pitting, crevice attack, and chloride-induced stress corrosion cracking (SCC). Its remarkable mechanical strength allows engineering teams to design thinner pipe wall thicknesses, reducing overall piping system weight and transportation costs without compromising structural safety or pressure ratings.
For international piping contractors, EPC engineering firms, and global metal distributors, our manufacturing facility ensures precise outer diameter (OD) and wall thickness tolerances, smooth internal surfaces, and competitive factory-direct pricing. All raw metal pipes strictly comply with recognized global quality standards such as ASTM A790 specifications.
These high-performance duplex stainless metal pipes are widely specified across chemical processing, offshore engineering, oil & gas, and heavy industrial sectors. Typical applications include:
We supply 2205 duplex stainless steel pipe products in both seamless and welded (EFW/ERW) configurations, covering a broad selection of standard outer diameters, SCH wall thicknesses (SCH 10S, SCH 40S, SCH 80S), and custom cut lengths.
Available surface and end options include standard mill pickled finish, bright annealed, mechanically polished, plain ends, beveled ends for welding, or threaded ends to meet exact field installation requirements.
Our experienced export logistics team guarantees prompt manufacturing lead times, seaworthy wooden crate or bundle packaging with protective end caps, and authentic Mill Test Certificates (MTC) accompanying every shipment for complete quality traceability.

2205 duplex stainless steel pipe provides higher strength and better resistance to chloride-induced corrosion than 316 stainless steel pipe. The most suitable material depends on the operating environment, design requirements, and fabrication process.
Yes. 2205 duplex stainless steel pipe can be welded using appropriate welding procedures and filler materials. Proper heat input and post-weld practices help maintain its corrosion resistance and mechanical properties.
2205 duplex stainless steel pipe is widely used in many seawater and chloride-containing environments because of its excellent corrosion resistance. The final material selection should always consider factors such as chloride concentration, temperature, flow conditions, and overall service environment.
It offers excellent resistance to seawater corrosion and maintains strength in humid and salt-rich conditions.
No. Strength is achieved through strain hardening rather than heat treatment.
Yes. It provides excellent weldability for structural fabrication.
Yes, it is commonly applied in tanks and pressure equipment.
Yes. It provides higher strength compared with most non-heat-treated aluminum alloys.
Yes. Thickness, width and temper can be adjusted based on project demand.
