ASTM A182 F347 is a specification for forged or rolled alloy and stainless steel pipe flanges, fittings, valves, and parts for high-temperature service.
The "F347" designation refers to the specific grade of stainless steel used in the flange, which is a stabilized austenitic stainless steel with niobium added for enhanced corrosion resistance and high-temperature strength.
"WNRF" stands for "Weld Neck Raised Face," which is a type of flange design. Weld neck flanges have a long tapered hub that is welded to the pipe, providing reinforcement and a smooth transition for the flow of fluids or gases. The raised face feature provides a sealing surface for gaskets.
Overall, an ASTM A182 F347 Stainless Steel WNRF Flange is a flange made from the specified grade of stainless steel, designed with a weld neck and raised face for use in high-temperature applications.
