Import Duplex Stainless Steel Pipe — Buy in Bulk from Supplier in China

The duplex stainless steel pipe offered by Ningbo Intelligent Stainless Steel Co., Ltd is manufactured from a duplex microstructure that blends austenitic and ferritic phases. The product is supplied in a range of diameters and wall thicknesses to match project specifications. It provides excellent resistance to pitting and crevice corrosion, making it suitable for seawater and aggressive chemical environments. The pipe conforms to ISO quality standards as indicated in the supplier’s documentation.

In the stainless‑steel industry, duplex grades such as UNS S32205 are commonly selected for their high yield strength and superior corrosion performance. Typical duplex pipe dimensions span outer diameters from 2 mm up to 1 200 mm with wall thicknesses ranging from 1 mm to 60 mm, although exact sizes must be confirmed per order. Standard mechanical properties include a minimum tensile strength of 620 MPa and a yield strength around 450 MPa, which are typical for this class of alloy. The material’s ability to operate at temperatures up to 300 °C without loss of strength aligns with the supplier’s claim of an extreme temperature capability.

These pipes are widely used in oil and gas refineries, power generation plants and chemical processing facilities where durability and corrosion resistance are critical. Importers should discuss minimum order quantities, preferred packaging (e.g., bundled coils or straight lengths) and shipping terms such as FOB or CIF directly with the supplier. Final trade conditions, including payment schedules and lead‑time estimates, are negotiated on a case‑by‑case basis.

Ningbo Intelligent Stainless Steel Co., Ltd is located at No .1018 Min'an Road, Jiangdong District, Ningbo, Zhejiang Province, China. The company is classified as an imported‑tier supplier with a harbor trust tier, indicating that it has been vetted for basic compliance and traceability. Its profile shows a response rate of 0 % and no recorded average response time, suggesting that inquiries may require proactive follow‑up.

The supplier lists duplex stainless steel pipe as its primary product offering and emphasizes compliance with ISO quality standards. No additional certifications, production capacity or client references are disclosed in the listing, so buyers should request detailed technical data sheets and factory audit reports before committing to large volumes.
