ASTM A182 / ASME SA182 F316L WNRF Flange
Overview
The ASTM A182 F316L WNRF (Weld Neck Raised Face) flange is another type of flange made from stainless steel grade 316L. It is designed to be welded to the end of a pipe or fitting for a strong and leak-proof connection. The "WNRF" designation indicates that the flange has a raised face on the sealing surface and a long tapered neck that provides reinforcement and allows for easy alignment of the bolt holes during installation. The ASTM A182 F316L WNRF flange is commonly used in high-pressure and high-temperature applications where a secure and reliable connection is required. It offers excellent corrosion resistance and mechanical properties, making it suitable for various industries such as oil and gas, chemical, and petrochemical.
