Four processing methods and technology of carbon steel flange

　　Now, carbon steel flange has been more and more applications, and we have not thought about when in use, the use of such a large carbon steel flange are used in what way out of it?

　　Forging method: by swaging machine will be at the end of the pipe or a department to be rushed out electric butterfly valve the outer diameter eliminated, commonly used swaging machine with rotary, connecting rod, roller type.

　　Rolling wheel method: in the tube to place the core check valve outside the week with the roller pressure, for the round edge processing.

　　The rolling method: as usual without mandrel, suitable for thick wall pipe inside round edge.

　　4 abscesses: A is placed in the inner tube rubber and above to punch the compression, the tube bulge forming; another style is hydraulic bulge forming, in the middle tube filled with liquid, depending on the liquid pressure pipe and drum into the required shape.

　　Carbon steel flange in the actual production and the development of the different ways and process for production and, according to the process and principle, on different aspects of the produce of great value and effect, in the actual production add certain elements increase the characteristics and value of carbon steel flange, good use features and value. Mainly refers to the steel mechanical properties depending on the carbon content in steel, and generally do not add a lot of alloy elements of steel, and is sometimes referred to as plain carbon steel or carbon steel. Carbon steel is also called carbon steel, refers to the iron carbon alloy carbon content less than 2% WC. Carbon steel in addition to carbon containing the general also contains a small amount of silicon, manganese, sulfur, phosphorus. Carbon steel flange in the actual production and production process protection, need to be paid attention to in the production of items and methods, the first welding a cross-sectional polygon polygon ring shell or closed at both ends of the multiple edges of fan-shaped shells, interior flushes the full pressure medium, subjected to internal pressure, internal pressure for use under the cross section by the polygon gradually became round, eventually becoming a circular ring shells. According to the need, a circular ring shell can be made of different carbon steel flange, in the actual use can show important characteristics, the process applies to the manufacture of stamping elbow diameter and stamping elbow diameter ratio greater than 1. 5 of the large elbow, is the ideal method for the manufacture of large carbon steel pipe.
