Asme B16.5 Class 300 5 Inch Sch40 Wnrf Flanges
Product Description – ASME B16.5 Class 300 5" SCH40 Weld Neck Raised Face (WNRF) Flange
SSM manufactures and supplies ASME B16.5 Class 300 5-inch Weld Neck Raised Face (WNRF) Flanges, designed for high-pressure and high-temperature piping systems. These flanges are typically made from stainless steel 304, 316, or carbon steel ASTM A105, providing excellent mechanical strength, corrosion resistance, and durability.
The Weld Neck Flange (WN Flange) features a long tapered hub that provides superior reinforcement and stress distribution, reducing the risk of flange or pipe failure under extreme conditions. The Raised Face (RF) ensures a secure, leak-proof seal when used with standard gaskets. This type of flange is easy to align and weld, making it suitable for critical piping systems in various industries.
All flanges are forged, machined, and heat-treated according to ASME B16.5 standards to guarantee precise dimensions and reliable performance.
