UNS N08221 ASME SB-423 Seamless Pipes, Tubes
The product is a seamless pipe and tube made from Nickel Alloy UNS N08221, also known as Alloy 211, conforming to ASME SB-423 and ASTM B423 specifications. These pipes are supplied by Shangdun Special Materials Co.Ltd., based in China. The alloy composition includes nickel, iron, chromium and molybdenum, delivering high‑temperature strength and corrosion resistance.
The supplier offers standard dimensions that are typical for the industry, ranging from 12 mm to 300 mm outer diameter with wall thicknesses between 2 mm and 25 mm, and lengths up to 12 m as a typical maximum. Heat treatment is typically annealed to improve ductility, and the material meets the typical pressure rating of 150 bar at 400 °C. Such specifications align with common practice for geothermal steam generator and fossil‑fuel boiler tubing. All pipes are packed in wooden crates with protective padding, a standard method for safe international transit.
Typical end users include plant engineers for geothermal power stations, boiler manufacturers and heat‑exchanger fabricators who require reliable performance under high temperature and corrosive conditions. Buyers usually request mill test certificates and chemical analysis reports to verify alloy composition before shipment. Trade terms are not disclosed in the listing; interested importers should confirm MOQ, lead time, Incoterms and payment conditions directly with Shangdun. The supplier states that custom sizes are available upon request, providing flexibility for project‑specific requirements.

Sourcing UNS N08221 ASME SB-423 Seamless Pipes, Tubes from Shangdun Special Materials Co.Ltd. - China Import Guide
Before placing an order, verify that the supplier can provide a current mill test certificate and a chemical analysis report that detail the exact composition of the UNS N08221 alloy. Confirm that the dimensions, wall thickness and pressure rating match your project requirements and ask for a dimensional inspection report if tight tolerances are needed.
Logistics should be clarified early: request the preferred Incoterm (for example FOB Shanghai or CIF Ningbo), the estimated lead time for the required size and any shipping method constraints. Discuss payment terms, such as a letter of credit or telegraphic transfer, and ensure that any advance payment aligns with the supplier’s standard policy.
Arrange for a pre‑shipment inspection by a recognized third‑party agency to check dimensional accuracy, surface condition and heat‑treatment compliance. Request the inspection report, as well as the packing list, certificate of origin and any relevant customs documentation to facilitate smooth clearance upon arrival.
