High-neck butt-welded flanges mainly have higher stiffness and load-bearing capacity of neck flanges. Its purpose is to transfer the pressure of the pipeline, thereby reducing the Frankie high stress concentration butt welding flange, also known as high neck flange, rigid, suitable for high pressure and temperature occasions. The main production processes are integral forging, forging, pressing, casting, rolling and so on. The main production equipment is lathe, drilling machine, CNC machine tools and so on. Applications: Boiler pressure vessel, petroleum, chemical industry, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries. It is convenient to install on site, and can omit the process of weld flapping and kneading. According to the standard, there are mainly flat butt welded steel pipe flange - GB9115.1, convex face welded steel pipe flange - GB9115.6.
