Butt weld flanges are not prone to deformation, provide good sealing, and are widely used. They require certain levels of stiffness and elasticity, as well as a proper tapering transition at the weld site; the distance between the weld and the joint surface is large, which prevents the joint surface from being deformed by welding temperatures. These flanges feature a relatively complex trumpet-shaped structure, making them suitable for pipelines subject to significant fluctuations in pressure or temperature, as well as for high-temperature, high-pressure, and low-temperature applications. They are generally used for connecting pipelines and valves with a PN rating of more than 2.5 MPa； It is also used in pipelines for transporting expensive, flammable, and explosive media.
