Duplex Steel Square Pipes
Duplex Steel Square Pipes offered by Naman Pipe and Tubes are fabricated from duplex stainless steel grade 2205, identified by UNS S32205 or S31803. The alloy contains 22 % chromium, 3‑5 % nickel, 3 % molybdenum and 0.14‑0.20 % nitrogen, delivering the chemistry required for duplex performance. The pipes are produced in accordance with ASTM A789 and EN 10217‑7 standards, which define dimensional tolerances and mechanical properties for welded stainless steel tube. These specifications are listed in the supplier’s description and form the baseline technical data.
Duplex 2205 square sections are known for approximately twice the yield strength of conventional austenitic grades, making them suitable for high‑pressure and corrosive environments. Typical industry practice supplies square dimensions ranging from 25 mm to 300 mm with wall thicknesses between 2 mm and 12 mm, tolerance often ±0.5 mm, and a mill‑finish surface. Naman Pipe and Tubes states that the pipes are intended for offshore platforms, chemical processing plants and structural construction, aligning with common applications for this alloy.
Importers generally source these pipes for refineries, desalination facilities and coastal infrastructure projects where durability is critical. While the listing does not disclose minimum order quantities, payment terms or lead times, buyers should confirm these details directly with the supplier. Shipping is typically arranged on a FOB basis from Indian ports, allowing the buyer to select freight forwarders and insurance. Prospective purchasers are encouraged to request mill test certificates and verify compliance with the cited standards before finalising the contract.
