2205 Duplex Stainless Steel Welded Tube
2205 duplex stainless steel welded tube, ASTM A790 duplex pipe, duplex stainless pipe, corrosion resistant tube, offshore stainless tube, and chloride resistant tubing.
Procurement Overview
2205 duplex stainless steel welded tube supplier programs focus on high strength with strong chloride corrosion resistance, especially for chloride stress corrosion, pitting, and crevice corrosion environments. Buyers may search for the same product as ASTM A790 duplex pipe, duplex stainless pipe, corrosion resistant tube, offshore stainless tube, chloride resistant tubing, duplex stainless tubing, super duplex 2507 reference, chemical plant piping, or refinery piping. It is used in offshore engineering and petrochemical projects, shipbuilding, electric power, and high-end machinery.
Manufacturing Notes
Available product data identifies stable production of high-precision sizes including 51 x 4 mm and 22 x 3 mm as reference examples. Orders should still be confirmed by drawing, grade, size, wall thickness, surface condition, welding requirements, and inspection documentation.
Buying Considerations
For 2205 duplex projects, clarify working medium, chloride exposure, offshore or marine exposure, temperature, joining method, and purchaser inspection requirements. This helps confirm whether 2205 is the correct grade and whether extra documentation is needed before production.
RFQ Checklist
Send grade confirmation, OD, wall thickness, length, application, working medium, chloride exposure, temperature range, joining method, documentation needs, inspection scope, packaging requirement, and quantity. If the project is offshore, petrochemical, shipbuilding, power, or high-end machinery, include the project specification or buyer standard where available.

Frequently asked questions
When should buyers consider 2205 duplex stainless steel tube?
It is commonly considered for more demanding corrosion environments or strength requirements than standard austenitic grades, such as seawater heat exchangers, offshore scrubbers, and chemical processing.
What is the pitting resistance equivalent (PREN) of 2205 duplex tube?
2205 duplex stainless steel (UNS S32205 / EN 1.4462) delivers a Pitting Resistance Equivalent Number (PREN = %Cr + 3.3%Mo + 16%N) of ≥ 35, compared to ~25 for 316L. This provides superior resistance to localized pitting and chloride stress corrosion cracking (SCC).
Can documentation requirements be specified?
Yes. Required material documentation (EN 10204 3.1 MTR, ferrite content check, corrosion test ASTM G48) and inspection items should be stated before quotation.
Is 2205 suitable for chloride-containing environments?
2205 is specifically developed for environments where chloride stress corrosion, pitting, or crevice corrosion resistance is critical, such as marine engineering, coastal chemical plants, and reverse osmosis desalination systems.
Can 2205 duplex welded tube be customized by size?
Yes. Size, wall thickness, length, surface condition, and inspection requirements can be reviewed by inquiry before quotation.
What information is needed before quoting 2205 duplex tube?
Include grade confirmation, OD, wall thickness, length, working medium, chloride exposure, temperature, joining method, documentation requirements, inspection scope, and quantity.
Should buyers compare 2205 with 304 or 316L?
Yes. 2205 offers roughly double the yield strength of 316L with significantly higher pitting resistance, often allowing wall thickness reduction while extending service life in corrosive media.
What buyer search terms are common for 2205 duplex tube?
Buyers may search for 2205 duplex stainless steel welded tube, ASTM A789 duplex tube, ASTM A790 duplex pipe, duplex stainless pipe, corrosion resistant tube, offshore stainless tube, chloride resistant tubing, duplex stainless tubing, super duplex 2507 reference, chemical plant piping, or refinery piping.
