Background

Flanges, also called flange collars or lugs, are parts of the shaft-to-shaft connection for connection between pipe ends, and also useful flanges on equipment inlets and outlets for connection between two pieces of equipment, such as speed reducer flanges. The flange connection or the flange joint refers to detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures.

The forged flange has higher strength than the conventional cast flange, and is one of the flange products with the best mechanical properties. The raw material of the forged flange is generally a tube blank, and then the tube blank is continuously beaten after being cut, so that the defects of segregation, looseness and the like in the steel ingot are eliminated, and the mechanical property of the forged flange is higher than that of a common cast flange by one grade.

At present, the existing flange plate is simple in structure, the strength of the existing flange plate is low, the flange plate is not easy to damage due to the fact that the strength is low, when connecting pipe fittings, the sealing effect between the pipe fittings is reduced, so that the using effect of the flange plate is affected, meanwhile, the flange plate is lack of reinforcement, the stress strength of the flange plate is reduced, the damage of the flange plate is further increased, the influence on the use of the flange plate is caused, and how to invent a high-strength forged flange to improve the problems is the problem to be solved currently.
