Quantity
The SS 316 WN Flange is a high-performance pipe flange engineered for demanding industrial applications requiring exceptional strength, leak-proof connections, and resistance to high temperature and high pressure environments . This 4-inch, Class 300LB weld neck flange is manufactured from premium forged stainless steel 316, a material renowned for its enhanced chloride resistance and corrosion resistance, making it ideal for marine, chemical, and aggressive fluid handling systems .
Design & Construction
This SS 316 WN Flange features a long tapered hub that ensures smooth stress distribution and reduces joint erosion, a critical advantage for high-pressure piping systems . The Raised Face (RF) design is the ASME B16.5 standard default for Classes 150 through 600, providing a reliable, high-integrity sealing surface . The Forged Steel construction method enhances structural integrity, eliminating porosity and ensuring superior mechanical properties over cast alternatives.
