The SAE butt weld flange is made up of two parts: the flange head and the welding sleeve. The flange head has a flat sealing surface that fits with another flange head’s sealing surface, as well as bolt holes for attaching the flange to another hydraulic component. To make a secure and leak-free connection, the welding sleeve is fitted over the tube or hose and welded.
SAE butt weld flanges are commonly composed of carbon steel or stainless steel, which provide strength and endurance in demanding operating environments. They come in a variety of diameters and pressure ratings to satisfy the demands of various hydraulic applications. The welded connection reduces the number of components required in a hydraulic system by eliminating the requirement for separate clamps or bolts. Nonetheless, suitable welding procedures must be employed to ensure a strong and lasting connection.
