Import Duplex Steel 2205 Pipe & Tube — Buy in wholesale FOB from Supplier in India

Unisteel Engineering supplies Duplex Steel 2205 Pipe & Tube made from UNS S32205 alloy, which contains 22 % chromium, 5 % nickel, 3 % molybdenum, 0.2 % nitrogen and the balance iron. The product conforms to ASTM A790 specifications and is offered in outer diameters from 6 mm up to 610 mm, available as welded or seamless tubes. Each tube is produced with a balanced austenitic‑ferritic micro‑structure that delivers high strength and resistance to chloride‑induced stress corrosion. The supplier lists the material composition and standard compliance as the core technical data.

Typical wall‑thickness selections range from 2 mm to 30 mm, giving pressure classes from PN16 to PN40 which meet most oil‑and‑gas and desalination plant requirements. Tensile strength of the duplex grade is approximately 620 MPa, and the density is about 7.8 g cm‑3, both typical for S32205 alloy. The alloy’s superior resistance to chloride stress corrosion cracking makes it a preferred choice for offshore pipelines and refinery heat‑exchangers. These characteristics align with standard industry expectations for high‑performance duplex pipe.

The pipes are commonly used by EPC contractors, refinery operators and marine engineering firms that need long‑service life in aggressive environments. Importers should request certification of the ASTM A790 compliance and verify the mill test report before finalising a purchase. Unisteel Engineering indicates that pricing is linked to current alloy surcharges and that bulk volumes may affect the trade terms, so buyers are advised to discuss FOB or CIF conditions directly with the supplier. MOQ, lead time and payment terms are not disclosed in the listing and must be confirmed during negotiation.

Unisteel Engineering is headquartered at Office No. 10, Abbas Building, B Wing, 1st Floor, Jalbhoy Street, Near Rubberwala Building, Mumbai 400 004, Maharashtra, India. The supplier is listed under the harbor trust tier on the marketplace, indicating a basic level of verification, and the platform records show a response rate of 0 % with no average response time available. The company presents itself as a dedicated source of duplex stainless‑steel pipe and tube products for industrial applications. No additional corporate history or production capacity details are provided in the listing.

The catalogue entry highlights the ability to supply both welded and seamless duplex 2205 pipe in the sizes described, sourced from certified mills that meet ASTM standards. Because the response metrics are currently low, prospective buyers should initiate contact through the platform’s messaging system and request a recent mill test report to confirm product conformity. Unisteel Engineering does not disclose specific lead‑time or minimum order quantities, so these parameters must be clarified before placing an order. Maintaining clear communication will help mitigate the lack of automated response data.
