High neck butt welding flange is mainly the neck of the higher flange stiffness, bearing capacity has been improved. Its purpose is to transfer the pressure of the pipeline, so as to reduce the high stress concentration in the French base butt welding flange, also known as the high neck flange, rigid, suitable for higher pressure temperature occasions. The main production processes are integral forging, forging and pressing manufacturing, casting, rolling, etc. The main production equipment is lathes, drilling machines, CNC machine tools and so on. Application: boiler and pressure vessel, petroleum, chemical industry, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries. Site installation is more convenient, can omit the weld beat knead process. According to the standard there are mainly flat butt welding steel pipe flange -GB9115.1, convex butt welding steel pipe flange -GB9115.6.
