Import 2205 Flange — Buy in Bulk from Supplier in China

The 2205 flange is a duplex stainless steel piping component designed for high-pressure industrial applications in oil and gas, chemical processing, and marine systems. This listing offers multiple flange face configurations including welding-neck (WN), slip-on (SO), plate (PL), blind (BL), threaded (TH), socket-welding (SW), long weld neck (LWN), and lapped flange/stub end (LF/SE) variants. The welding-neck design provides superior structural strength and stress distribution, making it suitable for demanding pressure vessel and pipeline installations where fatigue resistance is critical.

This duplex stainless steel 2205 (UNS S32205) flange combines austenitic and ferritic microstructures to deliver approximately twice the yield strength of conventional austenitic grades while maintaining excellent ductility and toughness. The material exhibits outstanding resistance to chloride-induced stress corrosion cracking and pitting, which is essential for marine environments and brackish water applications. Flanges are manufactured to meet ISO certification standards for quality management systems, and the product is available in various pressure ratings to accommodate different system design requirements.
