ASTM B366 WP904L-S 90° ELBOW LR STAINLESS STEEL BUTT WELD FITTINGS
Overview:
WP904L elbow is a type of pipe fitting made from grade 904L stainless steel. Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content that provides excellent corrosion resistance， especially in environments with high concentrations of sulfuric acid. WP904L elbow is commonly used in industries such as chemical processing， petrochemical， and oil and gas due to its excellent resistance to various corrosive media.
The elbow shape of the pipe fitting allows for changes in direction of the pipe while maintaining a smooth flow of the fluid or gas. WP904L elbow is available in various sizes and angles to suit different piping configurations. The fitting also conforms to the ASTM B366 standard specification for factory-made wrought nickel and nickel alloy fittings.
