    LAP JOINT STUB END WP904L STAINLESS STEEL BUTT WELD FITTINGS ASTM B366 UNS N08904


    LAP JOINT STUB END WP904L STAINLESS STEEL BUTT WELD FITTINGS


    Overview:


    WP904L is a high-alloy austenitic stainless steel that offers excellent corrosion resistance in various environments. A lap joint stub end, also known as a lap joint flange, is a type of piping component used to connect pipes of different materials or sizes. It consists of two parts: the stub end, which has a large outer diameter and a small inner diameter, and the backing flange, which is used to bolt the stub end to another flange or fitting.


    The WP904L lap joint stub end is made of this high-grade austenitic stainless steel material and is designed specifically for use in corrosive environments. Its special properties make it an ideal choice for demanding applications in industries such as chemical processing, food and beverage, and pharmaceuticals. The main advantage of a lap joint stub end is its ability to rotate freely, which allows for easy alignment and adjustment during installation.
